New technology useful for soft-tissue imaging in interventional radiology procedures
May 07, 2007Soft-tissue cross-sectional imaging acquired on a flat panel C-arm fluoroscopic unit located in the interventional radiology area is feasible and useful for interventional radiology procedures, avoiding the necessity of sending patients out to a CT scanner, according to a new study by researchers from the Baptist Cardiac & Vascular Institute in Miami, FL.
For the study, 35 patient examinations were conducted, covering a diverse range of both vascular and non-vascular clinical application scenarios. The on-location imaging technique was used to evaluate arterial vessel characteristics such as thrombus, calcification, and size. Additionally, the technique was utilized in the evaluation of collections before and after drainage procedures. The researchers found that in 80% of the patients, additional clinical information was obtained that directly affected interventional therapy.
"This new imaging option allows for CT-like imaging from the acquisition of a rotational X-ray data set," said Constantino Pena, MD, lead author of the study. According to the researchers, the new technology has the possibility of making patient visits more efficient for both the doctor and the patient.
"Our report demonstrates that in selected cases the technique may be helpful in the care of patients. It gives the interventional radiologist the ability to acquire CT-like volumetric soft tissue images in the interventional suite without having to transport the patient to a CT scanner," said Dr. Pena.
The full results of this study will be presented as an electronic exhibit Monday, May 7 through Thursday May 10 during the American Roentgen Ray Society's annual meeting in Orlando, FL.

Interventional Radiology Current Events and Interventional Radiology News RSSWhen seconds count: Interventional radiology treatment for pulmonary embolism saves lives
Catheter-directed therapy or catheter-directed thrombolysis-an interventional radiology treatment that uses targeted image-guided drug delivery with specially designed catheters to dissolve dangerous blood clots in the lungs-saves lives and should be considered a first-line treatment option for massive pulmonary embolism, note researchers in the November Journal of Vascular and Interventional Radiology.
Stanford study recommends change in treating pulmonary embolisms
William Kuo, MD, was the on-call interventional radiologist one Friday night three years ago when he received a call from the intensive care unit at Stanford Hospital & Clinics.
Lifestyle changes remain important in fighting peripheral arterial disease
Modifying the risk of peripheral arterial disease (or PAD)-with healthy lifestyle changes-remains vital to one's health, note researchers in a recent issue of the Journal of Vascular and Interventional Radiology.
Image-guided treatment for deep venous thrombosis could improve patients' long-term outcomes
Deep Venous Thrombosis (DVT) is a serious condition that involves the formation of a blood clot inside of a deep vein usually in the legs. A patient with DVT is typically treated with anticoagulants (blood thinners) however researchers have found that image-guided interventional radiology procedures may play a more central role in the long-term treatment of DVT.
Interventional radiology treatment for uterine fibroids: Safe, nonsurgical option
Uterine fibroid embolization-a minimally invasive interventional radiology treatment for women that cuts off blood flow to painful fibroids to kill the tumors-is highlighted as an appropriate treatment for women in a Clinical Therapeutics article in the Aug. 13 issue of the New England Journal of Medicine.
Patient Radiation Exposure During Interventional Procedures is a Concern for Some Developing Countries
Interventional radiology procedures are on the rise in developing countries and there is a significant need for optimization of these procedures to ensure patient safety.
Is RTA a new potential option for the treatment of hydatid cysts?
Current treatment of cystic echinococcosis is surgery or percutaneous aspiration, injection and reaspiration (PAIR) using hypertonic saline or ethanol.
Interventional radiology: From sidelines to mainstream for patients
The Society of Interventional Radiology hailed the extension of an American College of Radiology resolution in support of clinical patient management by vascular and interventional radiologists as an important reminder of the critical contribution these minimally invasive specialists bring to quality patient health care.
Large congenital and solitary intrahepatic arterioportal
A case report to be published on April 7, 2009 in the World Journal of Gastroenterology reported incidental findings of a large and solitary congenital APF in a 73-year-old woman.
Promising 3-year data: Saving limbs with drug-eluting stents
Attempts to treat critical limb ischemia in peripheral arterial disease (PAD) patients with below-the-knee angioplasty are still thwarted by restenosis (the re-narrowing of the artery at the site of angioplasty or stenting), the need for repeat treatments and the continued progression of atherosclerotic disease, leading to tissue death (gangrene) and amputation.
