PET scans are superior to CT scans

A study published by the American College of Radiology found that PET scans had a sensitivity rate of 93% compared to 46% for CT scans. Additionally, PET scans offered advantages over CT scans in terms of cost savings due to lower radiation exposure. The researchers recommend using PET scans for staging patients with suspected cancer s...

CT in the emergency room: Are CT examinations overused?

A recent study found that two-thirds of referring physicians had a suspected diagnosis before CT scans were ordered. The scan confirmed the diagnosis in 50-60% of cases. However, one-quarter of CT scans revealed diagnoses not considered based on symptoms. Abdominal CT is being used more often for appendicitis and other diseases.

Modified adenovirus offers new approach to treating aggressive brain tumors

A modified adenovirus, Delta-24-RGD, has shown improved infectivity and replication efficiency compared to the unmodified Delta-24. This leads to increased cytopathic effects and prolonged survival rates in mouse models of human glioma. The authors conclude that Delta-24-RGD may be an effective agent in treating gliomas.
