CT summation bolsters RFA's targeting accuracy
Merging multiple CT images increases the accuracy of probe repositioning during radiofrequency ablation treatments of various lesions, according to a recent study performed at Dartmouth-Hitchcock Medical Center.
Merging multiple CT images increases the accuracy of probe repositioning during radiofrequency ablation treatments of various lesions, according to a recent study performed at Dartmouth-Hitchcock Medical Center.
Author Dr. John M. Gemery, an assistant professor of vascular and interventional radiology at Dartmouth, successfully treated 40 patients using CT summation. The method allows for three or more probe placements to be seen at one time and takes about 30 seconds on a single-slice CT scanner to merge scans of different placements into a single set of images. According to Gemery, the process is much faster on newer multi-slice systems.
"Our discovery is an incremental step forward to improving image-guided treatments," Gemery said (AJR 2008:191:790-792).
New Literature Review Assesses Merits of Cardiac MRI After Survival of Sudden Cardiac Arrest
April 19th 2024While noting inconsistencies with the diagnostic yield of cardiac MRI in patients who survived sudden cardiac arrest, researchers cited unique advantages in characterizing ischemic cardiomyopathy (ICM) and facilitating alternate diagnoses.
Study of Ofatumumab for Multiple Sclerosis Shows 'Profoundly Suppressed MRI Lesion Activity'
April 17th 2024The use of continuous ofatumumab in patients within three years of a relapsing multiple sclerosis diagnosis led to substantial reductions in associated lesions on brain MRI scans, according to research recently presented at the American Academy of Neurology (AAN) conference.
