Article: Renal arteries: comparison of steady-state free precession MR angiography and contrast-enhanced MR angiography.
[show abstract] [hide abstract]
ABSTRACT: All participants provided informed consent to participate in this study, which was approved by the institutional review board. Breath-hold three-dimensional (3D) steady-state free precession (SSFP) magnetic resonance (MR) angiography was compared with 3D contrast material-enhanced MR angiography in patients suspected of having renal artery stenosis. Two radiologists assessed visualization of renal arteries and detection of vascular disease. With SSFP MR angiography, 39 of 41 renal arteries in 19 patients were correctly detected. Relevant stenoses were correctly identified with SSFP MR angiography in two patients. In two patients, SSFP MR angiographic data sets led to false-positive overgrading of vascular disease. Fast breath-hold 3D SSFP MR angiography appears to be feasible for MR angiography of renal arteries.Radiology 05/2006; 239(1):263-8. · 5.73 Impact Factor -
Article: CT and fluoroscopically guided percutaneous embolization treatment of a pseudoaneurysm associated with pancreatitis.
[show abstract] [hide abstract]
ABSTRACT: A novel approach to embolization treatment with a cyanoacrylate solution for a bleeding pseudoaneurysm associated with pancreatitis is described in the setting of a critically ill patient. Computed tomography and a C-arm fluoroscopic unit were used to guide percutaneous placement of a needle and injection of the embolic material. This technique represents an alternative form of embolization when traditional angiographic techniques are not possible.Journal of Vascular and Interventional Radiology 04/2005; 16(3):411-5. · 2.08 Impact Factor -
Article: Magnetic resonance imaging of the vascular system: a practical approach for the radiologist.
[show abstract] [hide abstract]
ABSTRACT: Contrast-enhanced magnetic resonance angiography (CE-MRA) has benefited from rapid technologic developments, including specific hardware and pulse sequence design. This article provides a brief practical overview of technique together with clinical examples of utility in daily application, from the view of an interventional radiologist. CE-MRA is rapidly replacing catheter-based diagnostic angiography for examination of the carotid arteries, aorta, renal arteries, and lower extremity.Topics in Magnetic Resonance Imaging 11/2003; 14(5):376-85. -
Article: Thoracic paravertebral block for analgesia following liver mass radiofrequency ablation.
[show abstract] [hide abstract]
ABSTRACT: A 66-year-old man presented for a second attempt of radiofrequency ablation of a metastatic carcinoid liver lesion. The first attempt using intravenous sedation was unsuccessful because of inadequate pain control and subsequent patient combativeness. Despite fentanyl being given during general anaesthesia, the patient complained of severe right flank pain after emergence. A thoracic paravertebral block was performed without complication and the patient's pain decreased to "3 out of 10" on a standard 10-point scale after 10 min, and "0 out of 10" after 30 min. The patient's pain score remained 0 throughout the following day, and no further analgesics were required. Thoracic paravertebral block can provide complete and lasting analgesia following hepatic radiofrequency ablation, and warrants further study for patients undergoing hepatic radiological interventions.The British journal of radiology 02/2008; 81(961):e23-5. · 2.11 Impact Factor -
Article: Advances in interventional radiology. The search for less invasive management sparks new approaches.
[show abstract] [hide abstract]
ABSTRACT: Many new, minimally invasive interventional radiology procedures are now viable alternatives to traditional invasive therapy. The radiology procedures can often be performed in the outpatient setting, and although expensive technology may be required, the overall cost to the patient may be lower in the long run. Endovascular repair of abdominal aortic aneurysms with stent grafts and radiofrequency tumor ablation are examples of rapidly expanding technologies in interventional radiology. Patient enthusiasm and interest are the primary forces driving these advances in management. Familiarity with these procedures is vital as medicine moves into the new millennium.Postgraduate Medicine 07/2001; 109(6):93-4, 97-9, 103-4. · 1.78 Impact Factor
