Chemical shift imaging in diagnosis of adrenal adenoma.
A 65 yrs old male patient and a known case of carcinoma of prostate with finding of a small adrenal mass on CT scan. MRI is done to rule out metastasis of adrenal. On in-phase and out phase imaging (Figs. 1,2) showing a significant loss of signals within the mass on out of phase imaging suggestive of lipid rich adrenal adenoma. The signal intensity drops below signals of spleen. Fig. 1 : In pha...
متن کاملEchoplanar chemical shift imaging.
A novel method of chemical shift imaging utilizing echoplanar imaging (EPI) has been developed for the purpose of improving the spatial resolution of metabolite images for the specific goal of high spatial resolution mapping of neuronal content. An EPI sequence was modified to allow temporal offsets of the 180 degree refocusing pulse that encode the chemical shift information into the phase of ...
متن کاملHeterogeneous living donor hepatic fat distribution on MRI chemical shift imaging
PURPOSE We evaluated the heterogeneity of steatosis in living donor livers to determine its regional differences. METHODS Between June 2011 and February 2012, 81 liver donors were selected. Fat fraction was estimated using magnetic resonance triple-echo chemical shifting gradient imaging in 13 different regions: segment 1 (S1), S2, S3, and each peripheral and deep region of S4, S5, S6, S7, an...
متن کاملImaging of the adrenal gland lesions*
With the steep increase in the use of cross-sectional imaging in recent years, the incidentally detected adrenal lesion, or "incidentaloma", has become an increasingly common diagnostic problem for the radiologist, and a need for an approach to classifying these lesions as benign, malignant or indeterminate with imaging has spurred an explosion of research. While most incidentalomas represent b...
متن کاملSubcutaneous lipid suppression via variable-density spiral sampling for full cortical coverage in chemical shift imaging
Introduction: Estimates of metabolites in the brain using large-FOV chemical shift imaging (CSI) are severely hampered by strong lipid signals even though the interfering signal arises from subcutaneous tissue. Since SNR in MR is proportional to voxel size [1] the low metabolite concentration, and therefore low SNR in spectroscopic imaging dictates large voxel size, and in turn, the spatial ext...
