Study Notes
Inflammation of Bile Ducts
- Inflammation of the bile ducts is called cholangitis.
Bile Pigment
- Bilirubin is the yellow pigment produced by the liver during the breakdown of old red blood cells.
Pancreatic Adenocarcinoma
- The most common location for pancreatic adenocarcinoma is the head of the pancreas.
Gallstone Location
- A gallstone located within the biliary tree is called choledocholithiasis.
Sphincter of Bile and Pancreatic Juices
- The Sphincter of Oddi controls the emptying of bile and pancreatic juices into the duodenum.
Acute Pancreatitis Sonographic Appearance
- An early sign of acute pancreatitis seen on ultrasound is a hyperechoic glandular echotexture.
Acutely Inflamed Pancreas Echogenicity
- The most common echogenicity of an acutely inflamed pancreas is hypoechoic.
Splenic Hemangioma Sonographic Appearance
- The most common sonographic appearance of a splenic hemangioma is anechoic.
Red Blood Cell Production
- Erythropoiesis is the process of making red blood cells.
Splenomegaly Common Cause
- Portal hypertension is the most common cause of splenomegaly.
Ultrasound Finding in Splenic Mass
- A 1-cm, rounded, echogenic mass in the spleen that does not produce acoustic shadowing suggests a lipoma.
Portal Veins Characteristics
- Portal veins do not carry deoxygenated blood away from the liver.
- Portal veins have darker walls compared to hepatic veins.
- Portal veins demonstrate hepatopetal flow.
Fatty Liver Clinical Findings
- Elevated liver function tests are a clinical finding associated with fatty liver infiltration.
Liver Diffuse Echogenicity
- A sonographic finding of a difficult-to-penetrate, diffusely echogenic liver is indicative of fatty liver disease.
Cirrhosis Common Cause
- Alcoholism is the most common cause of cirrhosis.
Liver Cancer Type
- Hepatocellular carcinoma is the most common form of liver cancer.
Hepatitis Clinical Findings
- Jaundice, fever and chills are clinical findings of hepatitis.
- Pericholecystic fluid is not a clinical finding of hepatitis
Gallbladder Wall Thickness
- The gallbladder wall should measure no more than 3 mm in thickness.
Gallbladder Blood Supply
- The cystic artery supplies blood to the gallbladder.
Cholelithiasis Definition
- Cholelithiasis is the presence of gallstones within the biliary tree.
Gallbladder Biliary Tree Connection
- The cystic duct connects the gallbladder to the biliary tree.
Gallbladder Diameter Limit
- The maximum diameter of the gallbladder should not exceed 5 cm.
Acute Cholecystitis with Necrosis
- Gangrenous cholecystitis is characterized by acute cholecystitis progressing to necrosis and abscess development within the gallbladder wall.
Retroperitoneum Structures
- The spleen is not located in the retroperitoneum. The aorta, psoas muscle and kidney are.
Tumor Involving IVC
- Renal cell carcinoma is a tumor that can invade the inferior vena cava (IVC) from a connecting vein.
Kidneys and Posterior Muscles
- The psoas and quadratus lumborum muscles lie posterior to the kidneys.
Adrenal Gland Location
- The right adrenal gland lies posterior to the right kidney.
Inferior Mesenteric Artery Supply
- The inferior mesenteric artery supplies the left transverse colon, descending colon,sigmoid colon, and rectum.
Aorta Diameter
- The normal diameter of the aorta in men is less than 23 millimeters.
Abdominal Aneurysm Causation
- Arteriosclerosis, or hardening of the arteries, is the most prevalent cause of abdominal aneurysms.
Renal Artery Direction
- The right renal artery is posterior to the inferior vena cava.
Pancreatic Neck Vessel
- The superior mesenteric artery is anterior to the third part of the duodenum and posterior to the neck of the pancreas.
Transducer Sterilization
- Autoclaving is the most effective method of sterilizing an ultrasound transducer.
Renal Cyst Appearance
- Normal renal cysts appear as thin sacs filled with water-like fluid and are typically harmless.
Staghorn Calculi
- Staghorn calculi are kidney stones that involve the renal pelvis and at least two calyces.
Renal Stone Appearance
- Renal stones typically cause posterior acoustic shadowing.
Polycystic Kidney Disease
- Polycystic kidney disease is an inherited disorder producing multiple cysts in the kidneys and can affect other organs, such as the liver.
Renal Failure Appearance
- Renal failure can cause a shrunken, hyperechoic kidney.
Angiomyolipoma Description
- Angiomyolipoma is a benign renal tumor consisting of vascular tissues, smooth muscle, and fat.
Wilm's Tumor Description
- A Wilm's tumor is a rare, kidney tumor that mostly occurs in children. It is characterized by a large, heterogeneous mass in the kidney.
Renal Cell Carcinoma Description
- Renal cell carcinoma is a malignant tumor of the kidney. It typically appears as a heterogeneous mass in the kidney.
Hydronephrosis Grade 1
- Hydronephrosis Grade 1 is characterized by dilated renal pelvis without dilation of the calyces.
Hydronephrosis Grade 3
- Hydronephrosis Grade 3 is characterized by moderate dilatation of the renal pelvis and calyces.
Hydronephrosis Grade 4
- Hydronephrosis Grade 4 is characterized by severe dilation of the renal pelvis and calyces and cortical thinning indicating renal atrophy.
Bladder Stone Appearance
- Bladder stones appear as an echogenic object within the bladder with accompanying acoustic shadowing.
Bladder Cancer Appearance
- Bladder cancer is characterized by a mass and wall thickening in the bladder.
Important Contrast Agents
- Gadolinium is the most common contrast agent for magnetic resonance angiography.
Hysterosalpingogram Procedure
- The main purpose of a hysterosalpingogram (HSG) is to evaluate the patency of the fallopian tubes.
Barium Enema Complications
- Barium embolism is a potential complication of a barium enema.
CT Colonography Purpose
- The primary purpose of CT colonography is to distend the colon for better visualization to prevent radiation exposure and to mitigate patient discomfort.
Angioplasty Balloon Purpose
- The primary function of a balloon catheter in an angioplasty procedure is to expand the narrowed artery.
CT Contrast Resolution
- CT contrast resolution is better than conventional film images.
CT Advantages
- The advantage of CT over other imaging modalities such as MRI and echocardiography is its use of ionizing radiation.
Gallbladder Connection
- The cystic duct connects the gallbladder to the biliary tree
Adrenal Insufficiency Causes
- Metastatic lesions, which is the spread of cancer from another part of the body, are a cause of adrenal insufficiency
