Temporal pole proton preoperative magnetic resonance spectroscopy in patients undergoing surgery for mesial temporal sclerosis.

Neurosurg Focus 2012 Mar;32(3):E3

Department of Neurosurgery, University Hospital of Larissa, University of Thessady, School of Medicine, Greece.

Object: The purpose of this prospective study was to compare the results of proton MR spectroscopy (MRS) in temporal poles in patients with unilateral mesial temporal sclerosis (MTS) with the histopathological findings of the resected temporal poles.

Methods: A total of 23 patients (14 male and 9 female) with a mean age of 25.2 years (range 17-45 years) were included in this study, which was conducted over a 4-year period. Read More

Simultaneous pancreas-kidney transplants in type I and type II diabetic patients with end-stage renal disease: similar 10-year outcomes.

Transplant Proc 2005 Mar;37(2):1283-4

Washington Hospital Center, Washington DC 20010, USA.

Introduction: Herein we report 10- to 15-year results of simultaneous pancreas-kidney (SPK) transplants in 135 type I and type II insulin-dependent diabetes mellitus (IDDM) patients.

Methods: Diabetes type was defined by the absence (type I) or presence (type II) of C-peptide. The freedom from dialysis and need for insulin defined graft survival. Read More

Multimodal metabolic imaging of cerebral gliomas: positron emission tomography with [18F]fluoroethyl-L-tyrosine and magnetic resonance spectroscopy.

J Neurosurg 2005 Feb;102(2):318-27

Department of Neurosurgery, Heinrich-Heine-University, Düsseldorf, Germany.

Object: The purpose of this study was to determine the predictive value of [18F]fluoroethyl-L-tyrosine (FET)-positron emission tomography (PET) and magnetic resonance (MR) spectroscopy for tumor diagnosis in patients with suspected gliomas.

Methods: Both FET-PET and MR spectroscopy analyses were performed in 50 consecutive patients with newly diagnosed intracerebral lesions supposed to be diffuse gliomas on contrast-enhanced MR imaging. Lesion/brain ratios of FET uptake greater than 1. Read More

Magnetic resonance spectroscopic determination of a neuronal and axonal marker in white matter predicts reversibility of deficits in secondary normal pressure hydrocephalus.

J Neurol Neurosurg Psychiatry 2004 Aug;75(8):1141-8

Department of Neurosurgery, Shiga University of Medical Science, Ohtsu, Japan.

Background: Normal pressure hydrocephalus (NPH) is considered to be a treatable form of dementia, because cerebrospinal fluid (CSF) shunting can lessen symptoms. However, neuroimaging has failed to predict when shunting will be effective.

Objective: To investigate whether 1H (proton) magnetic resonance (MR) spectroscopy could predict functional outcome in patients after shunting. Read More

In vivo magnetic resonance spectroscopy of human fetal neural transplants.

NMR Biomed 1999 Jun;12(4):221-36

Magnetic Resonance Spectroscopy Unit, Huntington Medical Research Institutes, Pasadena, CA 91105, USA.

To better define the survival and cellular composition of human fetal neurotransplants in vivo, we performed quantitative 1H MRS to determine the concentration of the neuronal amino acid [N-acetylaspartate] within MRI-visible grafts. In all, 71 grafts in 38 patients [24 Parkinson's disease (PD), 14 Huntington's disease (HD)] were examined, as well as 24 untreated PD and HD patients and 13 age-matched normal controls. MRI appearances of edema were present in three out of 71 grafts, the remainder being consistent with histologically identified viable neural transplant tissue. Read More
