RDMS Abdomen study plan

Label the peritoneal spaces and ligaments - greater sac, lesser sac, paracolic gutters, hepatorenal recess - on blank axial and coronal templates from memory.

Trace the portal triad, aorta, and IVC at four vertebral levels and state which organ each structure lies adjacent to.

Differentiate intraperitoneal, primarily retroperitoneal, and secondarily retroperitoneal organs, and list the secondarily retroperitoneal structures by name.

Build from memory a table assigning each abdominal organ its arterial supply and venous drainage.

Explain how a spectral Doppler waveform changes as stenosis severity increases, and rank waveform patterns from normal to post-stenotic.

Calculate the resistive index from three sets of supplied peak-systolic and end-diastolic velocities and interpret each against organ-specific norms.

Describe the expected spectral appearance of the aorta, SMA, renal artery, and hepatic artery in a fasting patient.

Correlate hepatic, renal, and splenic function with their expected perfusion patterns and state which waveform change signals dysfunction.

Classify focal liver lesions by echogenicity, vascularity, and posterior acoustic behavior into benign, indeterminate, and suspicious categories.

Distinguish acute from chronic cholecystitis and list the secondary signs that increase diagnostic confidence.

Compare renal, pancreatic, and splenic masses in a self-built matrix of location, echotexture, and associated findings.

Predict the sonographic findings of five diffuse diseases - including cirrhosis and fatty infiltration - before checking a reference, then correct every miss.

Differentiate true aortic aneurysm, dissection, and pseudoaneurysm using measurable criteria such as size thresholds, intimal flap, and the yin-yang sign.

Identify the direct and indirect signs of renal artery stenosis and of portal hypertension, including recanalization, varices, and ascites.

Evaluate IVC and hepatic vein Doppler for elevated right heart pressure and state which patterns suggest tamponade or constriction.

State, for each major abdominal vessel, the velocity or size threshold that triggers further imaging.

Detect free fluid in each dependent space on a FAST-type survey and rank those spaces by sensitivity for small volumes.

Describe the sonographic appearance of solid organ injury - laceration, hematoma, active extravasation - and state what makes a trauma study indeterminate.

Map expected postoperative anatomy after cholecystectomy, nephrectomy, bowel resection, and renal transplant, including normal fluid and gas patterns.

Differentiate expected postoperative changes from complications such as abscess, hematoma, bile leak, and anastomotic stenosis.

Predict how changing frequency, depth, and pulse repetition frequency alters resolution, penetration, and aliasing in a given image.

Explain the physical cause of shadowing, enhancement, reverberation, and refraction artifact, and identify each from a written description.

Select transducer frequency, focal zone, and gain for three patient-habitus scenarios and justify every choice.

Convert among frequency, period, wavelength, and propagation speed for soft tissue using the standard assumed speed.

Apply ALARA reasoning and output-display-index principles to justify settings changes in three described scenarios.

State the required disinfection level for each probe type and the infection-control steps for an endocavitary examination.

Outline the mandatory elements of a report for both an abnormal finding and a communicated critical result.

Re-test the two lowest-scoring domains from the week-4 test and write a correction note for every missed item.

Complete two full-length timed mock exams under test conditions and score each broken down by domain.

Rank all eight domains by score and rebuild a 20-item high-yield review for the bottom two.

Recite without notes the thresholds, formulas, and decision algorithms you built in weeks 1–7.
