[Ultrasonographic diagnosis of tumors of the gallbladder]
Abstract:
The role of echography in the diagnosis of gallbladder tumors was investigated. Benign tumors (papilloma and adenoma) were diagnosed in 2 patients and carcinoma in 18 subjects. This technique failed to diagnose carcinoma in 2 patients. Two more procedures had false-positive results (in one patient multiple clots in the dramatically enlarged bladder were taken for the tumor while ++post-inflammatory granulation in the other patient was mistaken for the tumor as well). Echographical signs of gallbladder tumors were presented, as were the criteria permitting one to differentiate carcinoma from other pathological formations in the gallbladder (echogenic bile, cholesterol polyps, cholecystitis, adenomyomatosis). High informative value of echographic investigation in the diagnosis of gallbladder tumors was noted.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
