Study suggests vasovagal reactions are rare in VC

Vasovagal reactions can result from overstimulation of the vagus nerve, and are a phenomenon best avoided. Emotional trauma and certain medications can produce reactions, as can conventional colonoscopy, according to published studies. Can virtual colonoscopy produce vasovagal reactions as well? Researchers from Italy performed a study to address this question.

Lung CAD shows limited sensitivity gains, finds nodules radiologists missed

Two studies presented at the recent RSNA meeting in Chicago underscored the clinical utility of computer-aided detection (CAD) for finding significant lung nodules with CT. They also served to highlight the limitations of current-generation lung CAD systems, most of which are based on common shapes of solid nodules.

Echo may be more accurate than ECG for triggering cardiac scans

Real-time ultrasound could offer significant advantages over the electrocardiogram for triggering heart scans, according to a preliminary study from the University of Michigan in Ann Arbor. The authors' ultrasound technique could potentially improve the quality and consistency of cardiac imaging with CT and MRI.

Long-term anticoagulant users show elevated coronary, aortic calcium

CHICAGO - Patients who take oral anticoagulants may risk developing significant coronary and aortic calcification. In a study that casts a wary eye on the routine use of the vitamin K antagonists such as warfarin, researchers from Aachen, Germany, found that long-term oral anticoagulant therapy was independently associated with increased calcium scores and valvular calcium deposits.

MRI immediately post MI yields important prognostic clues

CHICAGO - If you're looking for microvessel obstruction in patients with acute myocardial infarction, it's worth the rush to perform cardiac MRI within 48 hours after the event -- and within two minutes of injecting the contrast. You could potentially help your patients live longer.

Fine-needle aspiration biopsy useful for smallest lung nodules

CHICAGO - In the RSNA's interventional lung session on Wednesday, Dr. Demetris Patsios from the Mount Sinai Hospital in Toronto, Canada, presented a study on the efficacy of MDCT-guided fine-needle aspiration biopsy (FNAB) of subcentimeter nodules, concluding that FNAB is a useful tool, if less accurate than FNAB of larger lesions.

Ultralow-dose lung MDCT may still find ground-glass lesions

CHICAGO - Researchers from Japan presented findings from their study on the use of ultralow-dose CT and the detection of ground-glass lung opacities in a presentation yesterday at RSNA 2005. The results for low-dose CT lung screening advocates are encouraging.

Distinct CT perfusion parameters help assess HCC

CHICAGO - Hepatocellular carcinoma (HCC) is characterized by highly vascular tumors that progress rapidly yet quite variably from patient to patient. In a new study, researchers are attempting to determine whether perfusion imaging can be used to assess the prognosis of the individual patient, and perhaps help direct treatment.

CT obviates need for biopsy in pancreatic malignancy

CHICAGO - When typical CT features of pancreatic malignancy are present, there's no need for percutaneous biopsy, according to the results of a five-year study presented Monday at the RSNA meeting. As always, oncologists and patients may be hesitant to stop after imaging alone, but the additional information gleaned from biopsy could help direct patient management if other factors, particularly age, are taken into account.
