Decubitus Chest
4
Feb

Overview

Decubitus chest radiographs are obtained with the patient lying on the side to detect small pleural effusions. Fluid layers dependably on the dependent hemithorax and becomes visible as a meniscus. This view is helpful when upright imaging is not feasible.

Technique

Position the patient in lateral decubitus with the affected side down for fluid detection. Use a horizontal beam to demonstrate layering of pleural fluid. Ensure adequate exposure and include the entire hemithorax.

Clinical Indications

Decubitus views are indicated when small effusions are suspected or to differentiate free fluid from loculated collections. They are useful in trauma and bedridden patients. They complement standard chest radiographs for comprehensive evaluation.

Image Assessment

Look for layering fluid along the dependent lateral chest wall and blunting of the costophrenic angle. Assess for associated consolidation or atelectasis. Correlate with clinical findings and consider ultrasound or CT for further evaluation.

Chest AP Semi Upright

Feb

Overview

The AP semi upright chest radiograph is used when full upright positioning is not possible. The patient sits or reclines with the detector behind the back. This view provides better visualization than supine imaging while accommodating limited mobility.

Technique

Ensure the detector is positioned to capture the entire thorax and instruct the patient to inhale. Use support devices to stabilize the patient and minimize motion. Record the degree of upright positioning on the study.

Clinical Indications

Semi upright AP chest is useful for patients with limited tolerance for standing. It aids in assessing pulmonary edema pleural effusion and lines. It is a compromise between supine and full upright imaging.

Image Assessment

Account for projectional differences when evaluating heart size and lung volumes. Look for layering pleural fluid and central vascular congestion. Recommend upright imaging if clinical condition allows for improved assessment.

Chest AP Supine
4
Feb

Overview

The AP supine chest radiograph is used when patients cannot stand for upright imaging. The x ray beam passes from anterior to posterior with the patient lying on the table. Cardiac size may appear magnified compared with PA views.

Technique

Place the detector under the patient and center to the chest. Use appropriate exposure factors to penetrate the thorax in the supine position. Document patient position and limitations on the request form.

Clinical Indications

AP supine chest is indicated for critically ill or immobilized patients. It is commonly used in intensive care and emergency settings. Portable radiography enables timely assessment at the bedside.

Image Assessment

Interpretation accounts for projectional magnification and patient rotation. Evaluate for pneumothorax lines tubes and consolidation. Correlate with clinical status and consider follow up upright imaging when feasible.

Chest Lateral Upright
4
Feb

Overview

The lateral chest radiograph complements the PA view by showing retrosternal and retrocardiac spaces. The patient stands with left side against the detector and arms raised. This view improves localization of lesions and assessment of pleural effusion.

Technique

Position the patient with true lateral alignment and ensure no rotation. Instruct breath hold at full inspiration to maximize lung expansion. Use consistent exposure settings matched to the PA view.

Clinical Indications

Lateral chest is used to localize opacities and evaluate posterior lung fields. It helps detect small effusions and subtle consolidations. It is routinely obtained with the PA view for comprehensive assessment.

Image Assessment

Assess the retrosternal clear space and posterior costophrenic angles. Look for layering fluid and focal airspace disease. Correlate findings with the PA view for accurate interpretation.

Chest PA Upright
4
Feb

Overview

The PA upright chest radiograph is a standard view for evaluating the lungs and heart. The patient stands facing the detector with shoulders rolled forward. This view minimizes cardiac magnification and improves visualization of pulmonary markings.

Technique

Instruct the patient to take a deep inspiration and hold breath during exposure. Ensure the scapulae are out of the lung fields and the chin is elevated. Use appropriate exposure factors for body habitus.

Clinical Indications

PA upright chest is used for routine chest evaluation and screening. It assesses cardiopulmonary disease and follow up of known conditions. It is preferred when the patient can stand and cooperate.

Image Assessment

Evaluate lung fields heart size and mediastinal contours on the PA view. Check for symmetry and presence of lines tubes or devices. Compare with prior studies for interval change.

Whole Spine Lateral
4
Feb

Overview

Whole spine lateral radiographs evaluate sagittal alignment from cervical to sacral regions under physiologic load. They are used to assess global balance and plan corrective spinal surgery. Proper positioning ensures inclusion of all spinal segments.

Technique

Obtain a full length lateral radiograph with the patient standing and arms positioned to avoid obscuring the spine. Use consistent posture and include a calibration marker for measurements. Immobilize and instruct the patient to maintain natural stance.

Clinical Indications

Whole spine lateral views are indicated for deformity assessment adult spinal deformity and preoperative planning. They quantify sagittal vertical axis pelvic parameters and lumbar lordosis. Serial imaging monitors progression and postoperative outcomes.

Image Assessment

Measure sagittal vertical axis pelvic tilt pelvic incidence and lumbar lordosis. Assess for compensatory mechanisms and vertebral deformity. Report findings to guide surgical planning and alignment goals.

Temporomandibular Joint Panoramic
4
Feb

Overview

Panoramic TMJ projections provide bilateral overview of condylar position and joint space in a single acquisition. They are useful for screening degenerative change and gross asymmetry. Proper patient positioning ensures comparable bilateral images.

Technique

Use panoramic equipment with TMJ specific settings and instruct the patient to bite in centric occlusion. Center to the TMJ region and ensure head stabilization during rotation. Remove metallic objects that may cause artifacts.

Clinical Indications

Panoramic TMJ imaging is indicated for screening degenerative disease trauma and gross asymmetry. It complements dedicated TMJ open closed views and MRI for soft tissue evaluation. Use as part of dental and maxillofacial assessment.

Image Assessment

Compare condylar morphology joint space and symmetry between sides. Look for erosive change osteophytes and gross displacement. Recommend MRI for disc and soft tissue pathology when indicated.

Forefoot Weightbearing AP Oblique
4
Feb

Overview

Weightbearing AP oblique forefoot radiographs assess metatarsal alignment and forefoot deformities under physiologic load. The oblique projection profiles the lateral column and metatarsal heads. These views are useful for hallux valgus and metatarsal pathology assessment.

Technique

Obtain the oblique projection with the patient standing and bearing weight equally. Center to the metatarsal heads and use appropriate exposure for increased soft tissue thickness. Ensure consistent foot rotation for serial comparison.

Clinical Indications

Weightbearing oblique views are indicated for deformity assessment forefoot pain and preoperative planning. They reveal functional alignment and joint subluxation not seen on non weightbearing studies. Orthotic and surgical planning rely on weightbearing imaging.

Image Assessment

Evaluate metatarsal alignment hallux valgus angle and joint congruity under load. Assess for metatarsal head overload and subluxation. Report findings relevant to podiatric or orthopedic management.

Thumb AP and Lateral
4
Feb

Overview

AP and lateral thumb radiographs evaluate the first metacarpal and phalanges for fractures and dislocations. The thumb is positioned separately from the hand to avoid overlap. These views are standard for thumb trauma and degenerative assessment.

Technique

Obtain AP view with the thumb extended and the lateral view with the thumb in true lateral. Use tight collimation and a small focal spot for optimal detail. Immobilize the thumb to reduce motion.

Clinical Indications

Thumb series are indicated for trauma pain and suspected Bennett or Rolando fractures. They assess joint congruity and articular surface involvement. CT is used for complex intra articular fractures.

Image Assessment

Evaluate cortical continuity base of first metacarpal and articular surface for displacement. Assess for subluxation and associated soft tissue injury. Report findings relevant to hand surgery referral.

Scaphoid Axial View
4
Feb

Overview

The axial scaphoid view images the scaphoid in a different plane to better visualize the proximal pole and waist. It is obtained with specialized positioning to elongate the scaphoid. This view aids in detecting fractures that may be occult on standard projections.

Technique

Position the wrist in ulnar deviation and apply a specific tube angle to project the scaphoid axially. Center to the scaphoid and use tight collimation for detail. Immobilize the wrist to minimize motion artifact.

Clinical Indications

Axial scaphoid views are indicated when standard scaphoid projections are inconclusive and clinical suspicion remains high. They help detect proximal pole fractures and guide immobilization decisions. MRI or CT is used for definitive diagnosis when radiographs are negative.

Image Assessment

Inspect the scaphoid waist and proximal pole for cortical disruption and sclerosis. Evaluate for associated radial styloid fractures and carpal instability. Report findings and recommend advanced imaging if needed.
