SPIE: Is MRI-guidance the next step for IGRT?
May 21, 2010 -- Image-guidance has become an invaluable tool within radiation therapy, with recent years seeing a shift toward incorporating image-derived, patient-based information into the treatment process. At the same time, the industry has witnessed the emergence of advanced radiotherapy systems with integrated imaging capabilities.
Large study confirms CT's accuracy for acute appendicitis
May 20, 2010 -- SAN FRANCISCO - One of the largest CT studies to date of acute appendicitis has confirmed the modality's sky-high diagnostic accuracy. The results also showed that CT is relatively insensitive to imaging technique, though the researchers said they have come to favor the use of oral contrast.
