Diagnostic Accuracy of Standalone T2 Dixon Sequence Compared with Conventional MRI in Sacroiliitis.
Indian J Radiol Imaging
September 2022
The aim of this article was to assess the profile of T2-weighted (T2W) multipoint Dixon sequence and conventional sequences in magnetic resonance imaging (MRI) of sacroiliac joints for the diagnosis of active and chronic sacroiliitis. Prospective observational study. Thirty-seven patients with sacroiliitis underwent MRI with conventional coronal oblique short tau inversion recovery, T1W sequences, and T2W multipoint Dixon sequences.

Material And Methods: Our study included 100 patients, who were divided randomly into 2 groups. The patients included in Group A were scanned by SECT, and Group B members were scanned by DECT.
Diffusion weighted imaging in breast cancer - Can it be a noninvasive predictor of nuclear grade?
Indian J Radiol Imaging
March 2020
Background: DWI and ADC values are noninvasive MRI techniques, which provide quantitative information about tumor heterogeneity.
Aim: To determine the minimum and mean ADC values in breast carcinoma and to correlate ADC values with various prognostic factors.
Settings And Design: Prospective observational study.
Article Synopsis
- Seven isolates from spoiled fruits and vegetables were tested for their ability to produce pectinase, with one strain identified as MPTD1 being the most efficient.
- The study optimized various process parameters for pectinase production using Plackett-Burman and Box-Behnken designs, revealing that yeast extract, KHPO, incubation time, NaNO, and KCl negatively affect enzyme production.
- Positive factors for pectinase production included pH, MgSO, and pectin mass fractions, leading to a maximum enzyme activity of 2.43 (μM/mL)/min, marking the first report on pectinase production by this strain.
