Medical imaging of the gastrointestinal (GI) tract is crucial for the diagnosis of GI diseases. Historically, barium techniques have been the only available method. Although many diagnoses have been made on the basis of these exams, the diagnostic performance of these exams for certain abnormalities has been disappointing. Invite you to refer. | A core review of gastrointestinal imaging: Part 2 6 Liver QUESTIONS 1 Match each labeled structure (A to L) with the corresponding anatomic description (1 to 12). The image on the left labeled with structures A to F shows the liver above the horizontal plane of the right and left portal veins. The image on the right labeled with structures G to L shows the liver below this plane. Each option may be used only once. 2 What is the most likely cause of the liver abnormality in this patient with cardiac disease? A. Radiation therapy B. Total parenteral nutrition C. Hepatorenal syndrome D. Iodine deposition For patients in questions 3 to 7, select the most likely diagnosis (A to F) for the hepatic masses. Each option may be used once, more than once, or not at all. A. Cavernous hemangioma B. Hepatocellular adenoma C. Focal nodular hyperplasia D. Hepatocellular carcinoma E. Cholangiocarcinoma F. Abscess 3 A 63-year-old woman with right upper quadrant pain and a liver finding noted on ultrasound. Images are from an MRI using conventional extracellular gadolinium contrast. FS T2W, arterial phase T1W+gad, and delayed phase T1W+gad. 4 A 47-year-old woman with cirrhosis secondary to hepatitis C. Images from an MRI performed with conventional extracellular gadolinium contrast are shown. Top row: T2W and FS T1W. Bottom row: Arterial and delayed phase FS T1W+gad. 5 A 46-year-old woman with painless jaundice. Images from an MRI performed with conventional extracellular gadolinium contrast are shown. Top row: T2W and FS T1W. Bottom row: Arterial and delayed phase FS T1W+gad. 6 A 21-year-old woman found to have a liver lesion on ultrasound. Images from an MRI using hepatobiliary gadolinium contrast agent gadoxetate disodium (Eovist—Bayer HealthCare) are shown. T2W, arterial phase FS T1W+hepatobiliary gad, and 20-minute FS T1W+hepatobiliary gad. 7 A 51-year-old man with hepatitis B and cirrhosis. Images from
