[Radiodiagnosis of acute appendicitis]
Abstract:
Sixty acute appendicitis suspects with unclear clinical picture were examined with high-frequency ultrasound and native CT. The results of the examinations were compared with clinical data, surgical findings and histological evidence. Acute appendicitis was in 39 patients, other diseases of abdominal cavity and small pelvis--in 21. Sensitivity of CT was 95%, specificity--91.3%, accuracy--96.6%. Sensitivity of US was 92.3%, specificity--100%, accuracy--95%. The above parameters for non-invasive diagnostic methods were similar to ones for laparoscopy. Native CT and US are highly precise methods for diagnosis of acute appendicitis. They are preferable in unclear clinical situations, atypical location of the appendix, in children, elderly and aged patients, and in patients with mental disorders.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...
