Introduction The unsupressed water signal is often used as an internal reference for metabolite quantification in H-MRS. The water signal arises from different compartments of the human brain (brain matter BM and cerebral spinal fluid CSF) with large differences of T2 relaxation times between BM and CSF. Bi-exponential fitting of T2 relaxation times can be used to calculate the water signal at ...

BACKGROUND AND PURPOSE The detection of time-related maturational changes of the olfactory bulb (OB) on MR imaging may help early identification of patients with abnormal OB development and anatomic-based odor-cueing anomalies. MATERIALS AND METHODS Two separate reviewers retrospectively analyzed coronal T2-weighted spin-echo MR images of the frontobasal region in 121 patients. There were 22 ...

The nutritional problems in almond orchards have increased because of alkaline soils and insufficient nutrition. This study was done to evaluate the effect of nano-chelate super plus ZFM (Zinc, Iron and Manganese) spraying on quantitative and qualitative characteristics of almond commercial cultivars. This work was carried out in factorial experiment base on randomized complete block design wit...

Background Quantitative myocardial T2 is a promising technique to assess myocardial inflammation and edema (1). Recent implementations have utilized T2-prepared (T2prep) SSFP sequences to acquire a multiple T2 weighted images at different echo times, and generate T2 maps based on a 2-parameter (2P-fit) model of T2 decay (2,3). Recently, a 3-parameter fitting (3P-fit) model was found superior to...
