Arab Board Radiology Part 1 study guide
Arab Board Radiology Part 1 · Work through your exam, one topic at a time.
The Arab Board of Radiology Part 1 is the primary (written) examination that candidates sit before entering advanced training in diagnostic radiology under the Arab Board of Health Specializations. It is aimed at residents and trainees who have completed the foundational portion of their radiology training and need to demonstrate broad, working knowledge across the whole of the specialty before progressing to senior roles. The Arab Board Radiology Part 1 study guide has 12 sections and about 3,507 words.
01Physics, Instrumentation, and Radiologic Technology
You must be fluent in X-ray production (tube voltage, mA, exposure time, filtration, focal spot size and the line-focus principle), beam quality versus quantity, and how kVp shifts the spectrum. Understand attenuation as the sum of photoelectric absorption and Compton scatter, and how each varies with photon energy and atomic number - this underpins contrast.
298 words, about 1 min02Radiation Biology, Radiation Protection, and Safety
Know the stochastic (cancer, hereditary) versus deterministic (threshold) effects and their dose relationships. Understand DNA damage: direct versus indirect action, single- and double-strand breaks, and repair.
275 words, about 1 min03Contrast Media, Pharmacology, and Adverse Reactions
Understand iodinated contrast: ionic versus non-ionic, monomer versus dimer, osmolality, and viscosity. Higher osmolality drives chemotoxic effects; non-ionic low-osmolar agents reduce adverse reactions.
265 words, about 1 min04Basic Sciences Relevant to Radiology (Anatomy, Physiology, Pathology)
This domain tests cross-sectional anatomy and the physiology that explains imaging appearances. Know the mediastinal compartments and their contents, the segmental anatomy of the lung, the lobes and fissures, and the hilar relationships.
250 words, about 1 min05Chest and Cardiothoracic Imaging
Master the systematic reading of a chest radiograph: technical adequacy (rotation, inspiration, penetration), then lines and tubes, mediastinal contours, lungs, pleura, and bones. Understand the silhouette sign and air bronchograms.
262 words, about 1 min06Abdominal and Gastrointestinal Imaging
Understand the acute abdomen: free air (pneumoperitoneum), obstruction, ischemia, and perforation. Learn the CT signs of bowel obstruction (transition point, small bowel feces sign) and ischemia (pneumatosis, portal venous gas, reduced enhancement).
238 words, about 1 min07Genitourinary and Gynecologic Imaging
Know renal anatomy and the imaging of renal masses: simple cyst (Bosniak I) versus complex cysts (Bosniak II–IV) and the features that drive management. Understand renal cell carcinoma subtypes and the role of multiphasic CT/MRI.
251 words, about 1 min08Musculoskeletal Imaging
Understand bone structure and the radiographic appearance of fracture healing, plus the classic fracture patterns (transverse, spiral, comminuted, avulsion). Learn the principles of bone tumor evaluation: age, location (epiphysis, metaphysis, diaphysis), margin, matrix, and periosteal reaction (benign versus aggressive).
251 words, about 1 min09Neuroradiology
Master the imaging of stroke: CT signs of early infarction (loss of insular ribbon, dense MCA), the role of CT angiography and perfusion, and the concept of the penumbra. Understand intracranial hemorrhage (epidural, subdural, subarachnoid, intraparenchymal) and their CT appearances and evolution.
238 words, about 1 min10Head and Neck Imaging
Understand the anatomy of the neck spaces: parapharyngeal, retropharyngeal, submandibular, sublingual, and carotid spaces, and the lesions that arise in each. Learn the imaging of head and neck cancer: squamous cell carcinoma of the oral cavity, oropharynx, larynx, and hypopharynx, and the role of CT/MRI and PET-CT in staging and nodal disease.
253 words, about 1 min11Breast Imaging
Understand breast anatomy and the BI-RADS lexicon: mass, calcification, asymmetry, and architectural distortion, with final assessment categories 0–6 and their management implications. Learn mammographic technique and the value of additional views (magnification, spot compression, true lateral).
234 words, about 1 min12Pediatric Imaging
Understand the differences between pediatric and adult imaging: smaller body size, lower radiation tolerance, and the need for child-friendly protocols (ALARA, immobilization, play therapy). Learn the imaging of common pediatric emergencies: intussusception, pyloric stenosis, malrotation/volvulus, and appendicitis.
