Diagnosis of Renal Arteriovenous Malformation using 64-row Multiple Detector Computed Tomography and Computed Tomography Angiography
Reprint requests to: Dr. Chen-Pin Chou Department of Radiology, Kaohsiung Veterans General Hospital. No. 386, Ta Chung 1st Road, Kaohsiung 813, Taiwan, R.O.C. A 47-year-old woman presented to our hospital with chief complaints of hematuria and left flank pain. The patient denied any recent history of trauma, renal surgery or urinary tract disease. Arterial-phase CT and three-dimensional CT angi...
متن کاملTopological Analysis for Arteriovenous Malformations via Computed Tomography Angiography: Part 2: Practical Application
BACKGROUND In a previous study, the authors outlined a technique for calculating the number of abnormal vascular loop structures described in 3-dimensional computed tomography angiography. To be developed into a quantitative evaluation method for soft-tissue arteriovenous malformations (AVMs), the concept needs assessment of validity. METHODS Computed tomography angiography results of 19 soft...
متن کاملTopological Analysis for Arteriovenous Malformations via Computed Tomography Angiography: Part 1: Mathematical Concepts
BACKGROUND Evaluating the progression of soft-tissue arteriovenous malformation (AVMs) is still problematic. To establish a quantitative method, we took a morphological approach. METHODS Normal blood vessels in early-phase 3D-computed tomography angiography images are theoretically expected to be tree-like structures without loops, whereas AVM blood vessels are expected to be mesh-like struct...
متن کاملMagnetic resonance angiography of cerebral arteriovenous malformations.
Magnetic resonance (MR) angiography as a method for the long-term follow-up of cerebral arteriovenous malformations (AVMs) was assessed in 14 patients with cerebral AVMs. These patients were either untreated or treated with transarterial embolization and/or stereotactic radiosurgery (gamma knife). Two-dimensional- and three-dimensional (3D)-time-of-flight (TOF) techniques were useful for follow...
متن کاملComputed Tomography in the Diagnosis of Lesions in and Around the Saddle Area
Computed tomography is the method of choice for initial evaluation of pa tints with potential suprasellar masses. In our experience during the last 2 years C.T. has proved reliable for detecting or rulling out the presence of a suprasellar mass. It shows the direction and degree of parasellar extension and the presence of any calcific or cystic component of the lesion. When C.T. was negat...
