Study Notes

Abdominal/General Ultrasound Registry Review

This study guide covers abdominal and general ultrasound registry review topics, including anatomy and pathology.
It details different anatomical regions and pathologies within the abdomen, including the liver, gallbladder and biliary system, pancreas, spleen, renal and urinary systems, adrenal glands, and abdominal vascular structures.
It also covers miscellaneous abdominal topics, gastrointestinal system, chest and retroperitoneum, small parts, thyroid and neck, musculoskeletal and superficial areas, testicles, and prostate.
A table of contents is presented, detailing the different sections within the study guide.
Section related to Introduction to Abdominal Imaging provides descriptions for terms like anterior/superficial, posterior/deep, superior/cephalad, inferior/caudal, medial, lateral, proximal, and distal.
There is information on peritoneum, intraperitoneal and retroperitoneal organs.
Different pathology categories are included: diffuse, focal benign, infections, obstruction, trauma, and cancer.
Detailed information about the liver, including facts, anatomy, intersegmental/hepatic, intrasegmental/hepatic, and method of division is given.
The document also discusses liver variants, like Reidel's lobe and papillary process.
Different pathologies like diffuse liver disease and labs, and the role of different enzymes (ALT, ALP, AST) are included.
Information is provided on fatty liver infiltration (hepatic steatosis) and its clinical and sonographic manifestations.
The guide includes a section on cirrhosis and its clinical and sonographic characteristics, including nodular surface, micronodular, and macronodular types.
Details on portal hypertension, its causes, symptoms, and treatment (TIPSS) are included.
Portal vein compression (thrombosis) and Budd-Chiari syndrome are discussed.
The guide covers different types of infections like acute and chronic hepatitis, and liver abscesses.
Sections about various masses including focal benign masses (cysts, cavernous hemangioma, hepatocellular adenoma, lipoma, focal nodular hyperplasia), and malignant masses (hepatoma, metastasis, hepatoblastoma) are included.
