X-Ray Sternum AP & LAT at Chughtai Lab

X-Ray: Sternum – AP & LAT at Chughtai Lab

An X-Ray of the Sternum in Anteroposterior (AP) and Lateral (LAT) views is a specialized, non-invasive diagnostic imaging examination designed to evaluate the breastbone (sternum) and its surrounding joint structures. The sternum is a vital, flat bone located in the center of the anterior chest wall. It consists of three main anatomical parts: the manubrium at the top, the body in the middle, and the xiphoid process at the bottom. Together with the ribs, the sternum forms the protective rib cage that shields critical thoracic organs, including the heart, major blood vessels, and lungs, from external trauma. At Chughtai Lab, a leading diagnostic network in Pakistan, we utilize state-of-the-art digital radiography (DR) technology to perform this essential imaging study, ensuring high-resolution images with minimal radiation exposure for our patients.

The primary clinical value of a sternum X-ray lies in its ability to quickly and accurately detect structural abnormalities, fractures, joint dislocations, and bone pathologies. By obtaining two perpendicular views—the AP (or Posteroanterior, PA) view and the Lateral view—radiologists can thoroughly assess the alignment, density, and integrity of the bone. The AP view provides a frontal perspective, although the sternum can sometimes be obscured by the overlying thoracic spine and mediastinal structures. To overcome this limitation, the Lateral view is absolutely critical, as it isolates the sternum in profile, allowing for a clear evaluation of the bone’s anterior and posterior borders, displacement of fracture fragments, and the retrosternal space. This dual-projection approach is indispensable for diagnosing trauma-related injuries, post-surgical complications, and localized bone infections.

Digital radiography at Chughtai Lab offers significant advantages over traditional film-based X-rays. Our advanced imaging systems capture digital signals directly, producing exceptionally clear images within seconds. This rapid processing is particularly beneficial in emergency situations where a patient has sustained blunt chest trauma and requires immediate medical evaluation. Furthermore, digital imaging allows our consultant radiologists to manipulate image contrast and zoom in on specific areas of interest, enhancing diagnostic accuracy and reducing the need for repeat scans. This commitment to utilizing modern technology ensures that patients across Pakistan receive the highest standard of diagnostic care when they visit our facilities.

Clinical Procedure: What to Expect

Patient Preparation

Preparing for an X-Ray of the sternum is straightforward, requiring minimal effort from the patient. However, adhering to the following guidelines ensures the safety of the patient and the clarity of the radiographic images:

• Remove Metallic Objects: Patients must remove all metallic items from the chest and neck area, including necklaces, body piercings, clothing with metal zippers, buttons, snaps, or underwire bras. Metal can block X-rays and create artifacts on the image, potentially obscuring critical anatomical details.
• Wear Appropriate Clothing: It is recommended to wear loose, comfortable clothing. Depending on the clothing worn, you may be asked to change into a clean, hygienic hospital gown provided by Chughtai Lab.
• Inform About Pregnancy: Female patients must inform the radiographer if they are pregnant or suspect they might be. While the radiation dose from a chest or sternum X-ray is low, protective measures, such as placing a lead shield over the abdomen, are taken to safeguard the developing fetus.
• No Fasting Required: There are no dietary restrictions or fasting requirements for a plain sternum X-ray. You can eat, drink, and take your regular medications as prescribed by your physician.
• Bring Prior Medical Records: If you have had previous chest or sternum imaging (such as X-rays, CT scans, or MRIs), bringing those reports and films can be highly beneficial for comparative analysis.

During the Procedure

The entire procedure is performed by a certified radiological technologist and typically takes between 10 to 15 minutes. The process is completely painless and non-invasive. Here is what you can expect during the imaging session:

First, the technologist will verify your identity and explain the procedure. You will be guided into the X-ray room, where the digital radiography equipment is located. For the AP (or PA) projection, you will be positioned standing against the flat digital detector plate, or lying down on the X-ray table if you are unable to stand due to trauma. The technologist will position your chest carefully to align the sternum with the X-ray beam. To minimize the overlying shadow of the spine, the technologist may angle your body slightly (oblique position) or ask you to take shallow breaths during a slightly longer exposure time, which helps blur out the lung markings.

For the Lateral projection, which is the most diagnostic view for the sternum, you will be asked to stand sideways against the detector. You will be instructed to clasp your hands behind your back and pull your shoulders back as far as comfortable. This positioning pushes the sternum forward and pulls the shoulders out of the way, allowing for an unobstructed profile view of the breastbone. During the short exposure, which lasts only a fraction of a second, you will be asked to take a deep breath and hold it. Holding your breath helps stabilize the chest wall and prevents motion blur, ensuring the sharpest possible image. The technologist will operate the equipment from behind a protective lead-shielded barrier, maintaining visual and verbal contact with you throughout the test.

When is an X-Ray: Sternum – AP & LAT Performed?

Sternal Trauma and Fractures

A sternum X-ray is most frequently requested following blunt force trauma to the anterior chest wall. This commonly occurs during motor vehicle accidents, where the driver’s chest impacts the steering wheel, or during high-impact sports contact and severe falls. Symptoms of a sternal fracture include intense, localized pain over the breastbone, visible bruising, localized swelling, and pain that worsens with deep breathing, coughing, or laughing. Physicians order the AP and Lateral views to confirm the presence of a fracture, determine if the bone fragments are displaced, and assess for any immediate threat to the underlying mediastinal organs.

Post-Sternotomy Evaluation

Patients who have undergone open-heart surgeries, such as a coronary artery bypass graft (CABG) or valve replacement, require a median sternotomy, where the sternum is surgically split to access the heart. After the surgery, the bone is closed using surgical steel wires. If a patient experiences chest wall instability, a clicking or grinding sensation when moving, or persistent pain, a sternum X-ray is performed. This imaging helps thoracic surgeons evaluate the integrity of the sternal wires, check for wire breakage or displacement, and assess whether the two halves of the sternum are healing and fusing properly (sternal union) or if sternal dehiscence has occurred.

Suspected Osteomyelitis or Bone Infection

Osteomyelitis, or infection of the bone, can develop in the sternum, particularly as a complication of post-operative wound infections following cardiac surgery, or rarely through the spread of bacteria via the bloodstream. Patients with sternal osteomyelitis often present with localized chest wall warmth, redness, swelling, persistent pain, fever, and sometimes a draining sinus tract or purulent discharge from a surgical scar. A sternum X-ray is utilized as an initial imaging modality to detect early signs of bone destruction, cortical erosion, or periosteal reaction, helping clinicians initiate prompt antibiotic therapy or surgical debridement.

Localized Anterior Chest Wall Pain

Anterior chest pain can be an alarming symptom, often raising immediate concerns for cardiac events like myocardial infarction. Once cardiac, pulmonary, and esophageal causes of chest pain have been thoroughly ruled out through electrocardiograms (ECGs), blood tests, and clinical evaluation, musculoskeletal etiologies must be investigated. Conditions such as costochondritis (inflammation of the cartilage connecting the ribs to the sternum), sternoclavicular arthritis, or sternocostal joint degeneration can cause severe, localized pain. An X-ray of the sternum helps rule out underlying bone pathology, joint subluxation, or degenerative joint disease in these specific areas.

Evaluation of Palpable Sternal Masses

The development of a palpable lump, swelling, or mass over the breastbone requires careful diagnostic evaluation. While many chest wall masses are benign (such as lipomas or sebaceous cysts in the overlying skin), primary bone tumors of the sternum (like chondrosarcoma or osteosarcoma) or metastatic lesions from cancers elsewhere in the body (such as breast, lung, thyroid, or prostate cancer) can occur. Physicians request a sternum X-ray to determine if the palpable mass is originating from the bone itself, and to look for characteristic signs of bone destruction (osteolytic lesions) or abnormal bone growth (osteoblastic lesions).

What Does an X-Ray: Sternum – AP & LAT Detect?

An X-Ray of the sternum is a highly sensitive tool for identifying a wide range of structural, traumatic, and pathological conditions affecting the anterior chest wall. The primary findings that can be detected through this imaging study include:

• Sternal Fractures: Disruption in the bony cortex of the manubrium, body, or xiphoid process, which can be displaced or non-displaced.
• Sternal Wire Breakage: Fractured surgical wires in patients who have previously undergone a median sternotomy.
• Sternal Wire Displacement: Migration or pulling through of surgical wires from the bone, indicating sternal instability.
• Sternal Dehiscence: Separation of the two halves of a surgically split sternum post-sternotomy.
• Osteolytic Lesions: Areas of localized bone destruction, often appearing as dark spots, indicative of metastatic cancer, multiple myeloma, or severe infection.
• Osteoblastic Lesions: Areas of abnormal, dense bone formation, which can be associated with certain metastatic cancers or chronic inflammatory processes.
• Sternal Osteomyelitis: Radiographic signs of bone infection, including cortical erosion, bone destruction, and periosteal reaction.
• Sternoclavicular Joint Subluxation: Partial dislocation of the joint connecting the clavicle (collarbone) to the manubrium of the sternum.
• Sternoclavicular Joint Dislocation: Complete displacement of the sternoclavicular joint, which can be anterior or posterior.
• Sternocostal Joint Arthritis: Degenerative changes, joint space narrowing, or osteophyte formation at the joints where the rib cartilages meet the sternum.
• Congenital Anomalies: Structural variations present from birth, such as pectus excavatum (sunken chest) or pectus carinatum (pigeon chest).
• Xiphoid Process Fractures: Isolated fractures of the small, cartilaginous/bony tip at the bottom of the sternum, often caused by direct trauma.
• Soft Tissue Swelling: Increased density and thickness of the soft tissues overlying the sternum, indicating trauma, hematoma, or infection.
• Surgical Emphysema: The presence of air in the subcutaneous tissues overlying the chest wall, appearing as dark, gas-filled pockets.
• Retrosternal Hematoma: Indirect signs of bleeding behind the sternum, such as widening of the retrosternal soft tissue space.
• Sternal Sclerosis: Increased bone density or thickening of the bone cortex, often a response to chronic stress or low-grade infection.
• Bone Demineralization: Generalized loss of bone density (osteopenia or osteoporosis) visible in the sternal structure.
• Manubriosternal Joint Subluxation: Displacement at the joint between the manubrium and the body of the sternum, often seen in severe trauma.
• Retrosternal Mass: Soft tissue masses located immediately behind the sternum, which may compress adjacent mediastinal structures.
• Costal Cartilage Calcification: Age-related or physiological calcification of the cartilage connecting the ribs to the sternum.
