Proton Mr Spectroscopy: Higher Right Anterior Cingulate N-Acetylaspartate/Choline Ratio in Asperger Syndrome Compared with Healthy Controls
(Amer Soc Neuroradiology, 2007)
BACKGROUND AND PURPOSE: One former study reported higher prefrontal N-acetylaspartate (NAA) levels in patients with Asperger syndrome (AS). The objective of the current study was to test the hypothesis that patients with ...
Diagnostic Accuracy of the Constructive Interference in Steady State Sequence Alone for Follow-Up Imaging of Vestibular Schwannomas
(Amer Soc Neuroradiology, 2009)
BACKGROUND AND PURPOSE: Vestibular schwannoma (VS) is a benign, slow-growing tumor, and radiologic monitoring is an acceptable alternative to surgery in small lesions and in elderly patients, MR imaging with contrast is ...
Diffusion Mr Imaging Features Of Skull Base Osteomyelitis Compared With Skull Base Malignancy
(Amer Soc Neuroradiology, 2011)
BACKGROUND AND PURPOSE: SBO is a life-threatening infection that may have radiologic features similar to those of the neoplastic processes. The purpose of this study was to evaluate the DWI findings in SBO to facilitate ...
Distal Middle Cerebral Artery Aneurysms - Endovascular Treatment Results With Literature Review
(Edizioni Centauro, 2002)
Intracranial aneurysms of the distal intracranial arteries are uncommon lesions which are difficult to treat with surgical techniques. Distal middle cerebral artery (MCA) aneurysms constitute approximately 5% of all MCA ...
Diffusion-Weighted Mri For Detecting And Monitoring Cancer: A Review Of Current Applications In Body Imaging
(Aves, 2012)
Diffusion-weighted magnetic resonance imaging (MRI), Which involves the acquisition of a magnetic resonance signal related to the Brownian motion of water protons in tissue, has become a useful technique for assessing ...
Demystifying Aber (Abduction And External Rotation) Sequence In Shoulder Mr Arthrography
(Aves, 2014)
ABduction and External Rotation (ABER) sequence in magnetic resonance (MR) arthrography of the shoulder is particularly important to better depict abnormal conditions of some glenohumeral joint structures and surrounding ...
Different Forms Of Iron Accumulation In The Liver On Mri
(Aves, 2016)
Magnetic resonance imaging (MRI) is a well-established imaging modality to evaluate increased iron deposition in the liver. Both standard liver imaging series with in-phase and out-of-phase T1-weighted sequences for visual ...
Detection Of A Pseudoaneurysm In The Knee Joint With Doppler Imaging After Blunt Trauma
(Amer Inst Ultrasound Medicine, 2006)
Pseudoaneurysms are secondary to the disruption of vascular wall continuity and are characterized by a cystic structure and swirling blood flow inside. They are commonly seen in contemporary medical practice secondary to ...
Focal Sparing Of Iron And Fat In Liver Tissue In Patients With Hemosiderosis: Diagnosis With Combination Of R2*Relaxometry And Proton Density Fat Fraction Calculation By Mri
(Turkish Soc Radiology, 2011)
PURPOSE To demonstrate magnetic resonance imaging (MRI) findings of the focal sparing of iron and fat in liver tissue in patients with hepatic iron overload. MATERIALS AND METHODS We retrospectively reviewed 48 liver MRI's ...
Hyperform Balloon-Assisted Endovascular Neck Bypass Technique To Perform Balloon Or Stentassisted Treatment Of Cerebral Aneurysms
(Amer Soc Neuroradiology, 2007)
We describe a technique to bypass aneurysm neck using the HyperForm balloon to perform balloon- or stent-assisted enclovascular treatment of complex large or giant aneurysms with very wide neck in which other methods would ...
