Multi-Voxel 1H-MRS in Metachromatic Leukodystrophy

Multi-Voxel 1H-MRS in Metachromatic Leukodystrophy

Metachromatic leukodystrophy (MLD) is characterized by the accumulation of sulfatide sphingolipids in the brain and peripheral nerves. We report metabolite alterations recorded using multi-voxel proton spectroscopy of the brain in four children with MLD. The data revealed elevated myoinositol/creatine and lactate/creatine ratios as well as decreased N-acetyl aspartate/creatine ratios. We propos...

MR of childhood metachromatic leukodystrophy.

PURPOSE To investigate the MR findings of childhood metachromatic leukodystrophy (MLD). METHODS Nine MR imaging studies in seven children (five girls and two boys, 10 to 32 months old) with MLD were evaluated retrospectively for the extent and progression of white matter abnormalities and the presence of contrast enhancement. RESULTS All seven cases showed symmetric, confluent high signal i...

Metachromatic leukodystrophy: two sides of a coin.

Adult-type metachromatic leukodystrophy mimicking multiple sclerosis.

recessive lysosomal storage disease caused by a deficiency of arylsulphatase A (ASA). It is characterized by accumulation of sulphatide in the white matter in the central nervous system and peripheral nerves1. The disease is divided in four subtypes, according to onset, severity and progression of the disease: late infantile (before age 4), early juvenile (age 4 to 6), late juvenile (age 6 to 1...

Convex-Envelope Based Automated Quantitative Approach to Multi-Voxel 1H-MRS Applied to Brain Tumor Analysis

BACKGROUND Magnetic Resonance Spectroscopy (MRS) can measure in vivo brain tissue metabolism that exhibits unique biochemical characteristics in brain tumors. For clinical application, an efficient and versatile quantification method of MRS would be an important tool for medical research, particularly for exploring the scientific problem of tumor monitoring. The objective of our study is to pro...
