OMSB Diagnostic Radiology (OEDR) study plan

OMSB Diagnostic Radiology (OEDR) · Give each week a clear focus.

8 weeks · About 8 hours per week

Week 1

Neuroradiology (Brain, Head and Neck, Spine) & Physics, Instrumentation and Radiation Safety

  • Map the OMSB OEDR blueprint to a personal checklist, tagging each neuroradiology and physics topic as known, shaky, or unknown

  • Derive the CT Hounsfield unit scale and window/level effects from first principles and calculate window width/level for brain, bone, and soft-tissue settings

  • Explain MRI T1, T2, FLAIR, DWI, and ADC signal behavior for acute infarct, edema, and hemorrhage, and state which sequence best detects each

  • Review CT and MRI dose metrics (CTDIvol, DLP, SSDE, SAR) and state one practical protocol adjustment that lowers dose without losing diagnostic quality

  • Interpret 15 brain CT cases covering stroke, hemorrhage, mass effect, and herniation, writing a one-line finding and diagnosis for each

Your checkpoint

A 20-row neuroradiology/physics error log with the missed concept, correct principle, and a corrected one-sentence explanation for each row

Week 2

Neuroradiology (Brain, Head and Neck, Spine) & Physics, Instrumentation and Radiation Safety

  • Differentiate extra-axial from intra-axial lesions using dural displacement, CSF cleft, and gray-white junction signs on 10 cases

  • Classify head and neck masses by compartment (parapharyngeal, masticator, carotid, retropharyngeal) and list the key differential for each

  • Describe the degenerative, infectious, and neoplastic spine patterns on MRI and state which findings mandate urgent communication

  • Apply MRI safety screening rules: implant categories, gadolinium contraindications, and pregnancy considerations

  • Explain radiographic artifacts (beam hardening, partial volume, aliasing, motion) and identify them on provided case descriptions

Your checkpoint

A completed 25-question self-test on brain, head and neck, and spine imaging with a written rationale for every wrong answer

Week 3

Gastrointestinal and Abdominal Imaging & Genitourinary and Pelvic Imaging

  • Build a systematic search pattern for abdominal CT covering liver, biliary tree, pancreas, spleen, adrenals, kidneys, bowel, and peritoneum

  • Distinguish the common focal liver lesions (hemangioma, FNH, adenoma, HCC, metastasis) by multiphasic enhancement pattern

  • Outline the acute abdomen pathways for appendicitis, cholecystitis, diverticulitis, and bowel obstruction, including the preferred modality and key signs

  • Interpret renal and pelvic imaging: hydronephrosis grading, renal mass characterization, and adnexal lesion risk stratification

  • Explain when to choose ultrasound, CT, or MRI for abdominal and pelvic indications, factoring in radiation and contrast risk

Your checkpoint

A one-page abdominal/pelvic search-pattern card plus 20 annotated case vignettes with the leading diagnosis and the single most discriminating finding

Week 4

Gastrointestinal and Abdominal Imaging & Genitourinary and Pelvic Imaging & Contrast Agents, Patient Safety and Quality Improvement

  • Compare iodinated contrast and gadolinium agents by osmolality, concentration, and excretion route, and select the right agent for renal impairment

  • Apply contrast premedication, renal function thresholds, and metformin/thyroid precautions to clinical scenarios

  • Recognize and manage contrast reactions by severity, including the first-line drugs and doses for anaphylaxis

  • Describe quality-improvement methods (audit, PDSA, root-cause analysis) and apply one to a radiology reporting or workflow problem

  • Review radiation protection principles (ALARA, shielding, dose reference levels) and calculate effective dose for a common CT examination

Your checkpoint

A contrast-safety and QI one-pager with a decision table for renal impairment, reaction management steps, and one worked effective-dose calculation

Week 5

Thoracic Imaging & Cardiovascular Imaging

  • Develop a structured reading approach for chest radiographs and CT, and apply it to 20 cases of consolidation, effusion, pneumothorax, and mediastinal widening

  • Classify interstitial lung disease patterns (UIP, NSIP, organizing pneumonia, hypersensitivity) and match each to typical CT findings

  • Stage lung cancer using TNM principles and identify the key CT features that change management

  • Interpret coronary CTA, cardiac MRI, and CT pulmonary angiography for stenosis, pulmonary embolism, and cardiomyopathy, including when each test is indicated

  • Explain aortic dissection, aneurysm, and intramural hematoma on CT angiography and state the urgent findings to report

Your checkpoint

A thoracic/cardiovascular case portfolio of 15 cases, each with a structured report line (findings, impression, recommendation) and a self-grade against a model answer

Week 6

Musculoskeletal Imaging & Breast Imaging

  • Apply a systematic approach to bone and joint radiographs, including fracture description, alignment, and joint-space assessment

  • Differentiate benign from aggressive bone lesions using margin, matrix, periosteal reaction, and soft-tissue components

  • Describe the MRI patterns of ligament, meniscal, rotator cuff, and tendon injury and state the most sensitive sequence for each

  • Explain BI-RADS categories, mammographic density, and the workup pathway for a screen-detected abnormality

  • Compare mammography, tomosynthesis, ultrasound, and MRI for breast screening and diagnosis, including their limitations

Your checkpoint

A musculoskeletal and breast rapid-review sheet covering 10 fracture/lesion descriptors and the full BI-RADS category table with management for each

Week 7

Pediatric Radiology & Nuclear Medicine and Molecular Imaging

  • Adapt imaging choices to pediatric patients: modality selection, sedation avoidance, and radiation-sparing strategies

  • Recognize pediatric-specific patterns such as intussusception, pyloric stenosis, malrotation, and non-accidental trauma

  • Explain radiopharmaceuticals, biodistribution, and common artifacts for bone scan, PET/CT, V/Q, and thyroid imaging

  • Interpret PET/CT staging and response patterns for common cancers and distinguish physiologic from pathologic uptake

  • Apply radiation dosimetry concepts in nuclear medicine and compare risk communication for pediatric and adult studies

Your checkpoint

A pediatric/nuclear medicine comparison table of 12 examinations with indication, dose category, and key interpretation pitfall for each

Week 8

Interventional Radiology and Vascular Procedures & Contrast Agents, Patient Safety and Quality Improvement
