Innovative MDCT raises the bar in esophageal cancer staging
By Eric Barnes
Esophageal cancer is highly curable when caught early, but usually fatal when advanced, making accurate staging crucial. Researchers from Japan are improving CT's ability to stage esophageal cancer. A group from Kyoto compared arterial- to venous-phase imaging for esophageal cancer, while a team from Chiba used ECG gating to reduce motion artifacts in assessing pericardial invasion of advanced esophageal cancer.

Crank call: Imaging exposes major brain alterations in meth abusers
By Shalmali Pal
What's the connection between meth and medical imaging? That would be in the brain, which sustains a "forest fire of damage," from meth abuse, according to one imaging expert. Neurology and mental health specialists are turning to MRI and PET to learn more about what draws people to meth, what keeps them on it, and how they might get off the drug.

Study reconfirms that MDCT can replace c-spine x-rays
By Tracie L. Thompson
WASHINGTON, DC - Helical CT allows trauma patients with potential c-spine injuries to skip the delay and difficulties of c-spine x-rays and go straight to CT. However, evidence for altering the standard of care was lacking. But findings from a West Virginia University study support the new practice, according to a presentation at this week's American Academy of Orthopaedic Surgeons (AAOS) meeting.

Enthesopathy on shoulder MRI may tag severity of rotator cuff tears
By Jerry Ingram
WASHINGTON, DC - Presurgical MRI may identify enthesopathy in patients with rotator cuff tears, according to a presentation Thursday at the 2005 American Academy of Orthopaedic Surgeons (AAOS) meeting. Enthesopathy can be an important secondary marker for determining the presence and severity of rotator cuff disorders, helping clinicians choose candidates for surgery.

Skip the cardiac imaging prior to hip fracture repair
By Tracie L. Thompson
WASHINGTON, DC - In an ideal world, patients who could benefit from coronary revascularization would receive that intervention before undergoing some other major noncardiac surgery. But it appears that preoperative cardiac clearance prior to hip fracture repair is mostly a path to poorer outcomes, according to research presented at the 2005 American Academy of Orthopaedic Surgeons (AAOS) meeting.
