Evaluate Extremity Radiographs - ARRT Radiography Exam
- What is the minimum anatomical inclusion for an AP foot radiograph?
- Phalanges, metatarsals, and tarsals. Includes all forefoot and midfoot bones to assess comprehensive foot anatomy and alignment.
- What is the minimum anatomical inclusion for an AP ankle radiograph?
- Distal tibia/fibula, talus, and mortise. Encompasses distal leg bones and ankle joint for evaluating stability and mortise space.
- Identify the positioning error: Mortise ankle shows distal tibiofibular overlap.
- Insufficient medial rotation for mortise. Overlap signifies improper leg rotation, failing to open the mortise for clear joint assessment.
- Which appearance confirms correct PA finger positioning regarding rotation?
- Equal concavity of phalangeal shafts. Indicates no rotation, ensuring symmetric visualization of joint spaces and bone contours.
- What is the minimum anatomical inclusion for an AP hip radiograph?
- Proximal femur and acetabulum. Captures the hip joint formation for assessing femoral head position and acetabular coverage.
- What is the minimum anatomical inclusion for an AP elbow radiograph?
- Distal humerus and proximal radius/ulna. Covers the elbow joint components for proper assessment of articulation and potential fractures.
- What is the minimum anatomical inclusion for a PA hand radiograph?
- All phalanges, metacarpals, and carpals. Provides comprehensive coverage of hand bones to evaluate injuries or pathologies across all segments.
- What is the minimum anatomical inclusion for an AP thumb radiograph?
- Entire thumb and trapezium. Captures the full thumb anatomy including its unique carpal connection for accurate assessment.
- What is the minimum anatomical inclusion for an AP tibia-fibula radiograph?
- Ankle and knee joints included. Covers both lower leg joints to assess full bone length and articular surfaces.
- What is the minimum anatomical inclusion for an AP forearm radiograph?
- Wrist and elbow joints included. Encompasses both proximal and distal joints to fully evaluate forearm length and articulations.
- What is the minimum anatomical inclusion for an AP shoulder radiograph?
- Proximal humerus, scapula, and clavicle. Visualizes key shoulder girdle elements to assess joint stability and bony integrity.
- What is the minimum anatomical inclusion for an AP knee radiograph?
- Distal femur, proximal tibia/fibula, patella. Visualizes knee joint components including the patella for evaluating alignment and pathology.
- Identify the positioning error: Lateral knee shows non-superimposed femoral condyles.
- Knee is rotated; not a true lateral. Non-overlap indicates internal or external rotation, distorting condyle profiles in lateral view.
- What is the minimum anatomical inclusion for an AP clavicle radiograph?
- Entire clavicle with both AC and SC joints. Ensures complete visualization of the clavicle and its sternal and acromial articulations for injury detection.
- What is the minimum anatomical inclusion for an AP finger radiograph?
- Entire digit and distal metacarpal. Ensures visualization of the complete finger structure and its articulation with the hand for diagnostic evaluation.
- Which appearance confirms a true lateral finger radiograph?
- Phalangeal condyles superimposed. Shows perfect lateral positioning with overlapped condyles for accurate joint evaluation.
- What is the minimum anatomical inclusion for an AP humerus radiograph?
- Shoulder joint and elbow joint included. Incorporates both articulations to evaluate the entire bone and associated joint pathologies.
- Identify the positioning error: AP ankle shows a closed tibiotalar joint space.
- Insufficient dorsiflexion or rotation. Closed space results from inadequate foot positioning, obscuring joint evaluation.
- Which appearance confirms a true lateral wrist radiograph?
- Distal radius/ulna superimposed; pisiform mid-scaphoid. Confirms lateral alignment through bone overlap and carpal positioning for true projection.
- What is the minimum anatomical inclusion for an AP or PA wrist radiograph?
- Distal radius/ulna and all carpals. Includes essential forearm and carpal structures to assess wrist joint integrity and alignment.
- Which appearance confirms correct PA hand positioning regarding rotation?
- Equal concavity of metacarpal shafts. Demonstrates absence of rotation, allowing uniform assessment of hand bone alignment.
- What is the minimum anatomical inclusion for an AP toe radiograph?
- Entire digit and distal metatarsal. Captures the full toe structure and its metatarsal connection for diagnostic purposes.
- What is the minimum anatomical inclusion for an AP femur radiograph?
- Hip joint and knee joint included. Includes proximal and distal articulations to assess the entire femur and joint integrity.
- Identify the positioning error: AP elbow shows radial head superimposed by ulna.
- Elbow is rotated; not a true AP. Superimposition indicates lateral or medial rotation, preventing clear visualization of the radial head.
