Abdominal Ultrasound Course

Lesson 1 • Transducer Technology and Selection

Explains piezoelectric crystal function, transducer types, and frequency trade-offs. Guides appropriate probe selection for abdominal structures.

Lesson 2 • Machine Controls and Optimisation

Covers gain, time-gain compensation, depth, and harmonic imaging controls. Optimising these settings is essential before any diagnostic scanning begins.

Lesson 3 • Common Ultrasound Artefacts

Identifies acoustic shadowing, enhancement, reverberation, and mirror artefacts. Teaches recognition to avoid misdiagnosis in abdominal scanning.

Lesson 4 • Image Formation and Modes

Describes B-mode, M-mode, and Doppler imaging modes and their clinical roles. Connects physics to the visual output seen on the ultrasound screen.

Lesson 1 • Aorta, IVC, and Mesenteric Vessels

Describes the retroperitoneal course of major vessels and their branching patterns. Vascular anatomy is critical for Doppler assessment and mass characterisation.

Lesson 2 • Abdominal Quadrants and Regions

Reviews the nine-region and four-quadrant systems as spatial reference frameworks. Provides the navigational language used throughout clinical scanning protocols.

Lesson 3 • Liver and Biliary System Anatomy

Details hepatic lobes, segments, ligaments, and biliary ductal anatomy. Foundational for recognising normal liver architecture and biliary pathology.

Lesson 4 • Kidneys, Ureters, and Bladder

Covers renal cortex, medulla, sinus, and collecting system anatomy with ureteral course. Prepares students to identify normal renal architecture and measure accurately.

Lesson 1 • Probe Handling and Ergonomics

Teaches grip, pressure application, and wrist mechanics to reduce operator fatigue and injury. Correct ergonomics also improves probe stability and image consistency.

Lesson 2 • Patient Preparation Protocols

Covers fasting requirements, bowel preparation, and bladder filling strategies. Preparation directly determines image quality for biliary and pelvic structures.

Lesson 3 • Standard Scanning Planes

Defines transverse, sagittal, coronal, and oblique imaging planes with probe orientation conventions. Consistent plane use enables reproducible measurements and comparison studies.

Lesson 4 • Patient Positioning Techniques

Covers supine, left and right lateral decubitus, and upright positions for organ access. Repositioning overcomes bowel gas and rib shadowing obstacles.

Lesson 1 • Diffuse Liver Disease Patterns

Identifies sonographic features of fatty liver, cirrhosis, and hepatitis. Recognising diffuse disease patterns guides clinical management and further workup.

Lesson 2 • Hepatic Doppler Assessment

Applies colour and spectral Doppler to evaluate portal hypertension, hepatic vein flow, and vascular thrombosis. Doppler findings directly influence staging and treatment decisions.

Lesson 3 • Focal Liver Lesion Characterisation

Differentiates cysts, haemangiomas, focal nodular hyperplasia, and metastases by echogenicity and margins. Accurate characterisation determines urgency of further imaging.

Lesson 4 • Liver Measurement and Reporting

Standardises hepatic measurement techniques and structured reporting elements. Consistent reporting ensures clinical utility and medicolegal defensibility.

Lesson 1 • Normal Gallbladder Sonographic Anatomy

Defines normal gallbladder dimensions, wall thickness, and lumen appearance. Establishes the baseline for detecting subtle early pathology.

Lesson 2 • Acute and Chronic Cholecystitis

Recognises sonographic Murphy's sign, wall thickening, and pericholecystic fluid in acute cholecystitis. Differentiates acute from chronic and acalculous forms.

Lesson 3 • Gallbladder Polyps and Wall Lesions

Differentiates cholesterol polyps, adenomas, and carcinoma by size, vascularity, and morphology. Size thresholds guide surveillance and surgical referral decisions.

Lesson 4 • Cholelithiasis and Biliary Sludge

Identifies gallstones by echogenicity, shadowing, and mobility, and distinguishes sludge from stones. Cholelithiasis detection is the most common biliary ultrasound indication.

Lesson 1 • Renal Doppler and Vascular Assessment

Measures resistive index, evaluates renal artery stenosis, and assesses transplant vascularity. Doppler findings complement structural assessment in medical renal disease.

Lesson 2 • Renal Calculi Detection

Identifies renal stones by echogenicity and posterior shadowing, including non-shadowing small stones. Compares ultrasound sensitivity with other imaging modalities.

Lesson 3 • Normal Kidney Sonographic Appearance

Establishes normal renal size, cortical echogenicity, and corticomedullary differentiation. Provides the reference standard for detecting parenchymal disease.

Lesson 4 • Hydronephrosis and Obstruction

Grades hydronephrosis severity and identifies ureteral jets to assess obstruction. Grading guides urgency of urological intervention.

Lesson 1 • Abdominal Aorta and Aneurysm

Measures aortic diameter at standard levels and identifies aneurysm morphology and thrombus. Aortic ultrasound is a critical screening and surveillance tool.

Lesson 2 • Splenic Sonographic Evaluation

Measures spleen size, assesses echogenicity, and identifies focal lesions and splenomegaly causes. Splenic findings often reflect systemic disease processes.

Lesson 3 • Retroperitoneal Masses and Lymph Nodes

Identifies retroperitoneal lymphadenopathy, haematomas, and fibrosis by location and echogenicity. Retroperitoneal findings often indicate systemic malignancy or haemorrhage.

Lesson 4 • Pancreatitis and Pancreatic Pathology

Identifies acute and chronic pancreatitis features, pseudocysts, and ductal dilation. Recognises sonographic signs that indicate severity and complications.

Lesson 1 • Structured Reporting and Communication

Constructs complete, structured ultrasound reports with appropriate clinical recommendations. Effective reporting closes the loop between imaging findings and patient care.

Lesson 2 • Ascites and Peritoneal Assessment

Identifies free fluid, loculated ascites, and peritoneal nodularity in systematic scanning. Distinguishes transudative from exudative patterns by fluid characteristics.

Lesson 3 • Multi-Organ Differential Diagnosis

Applies cross-organ reasoning to common clinical presentations such as RUQ pain and jaundice. Integrative thinking reduces unnecessary additional imaging.

Lesson 4 • Contrast-Enhanced Ultrasound Principles

Introduces microbubble contrast agents, injection technique, and enhancement phases. CEUS improves lesion characterisation beyond grayscale and Doppler capabilities.
