Can Diffusion-Weighted Imaging be a Gold Standard Method for Acute Appendicitis? A Comparative Study

Acute appendicitis: what is the gold standard of treatment?

McBurney's procedure represented the gold-standard for acute appendicitis until 1981, but nowadays the number of laparoscopic appendectomies has progressively increased since it has been demonstrated to be a safe procedure, with excellent cosmetic results and it also allows a shorter hospitalization, a quicker and less painful postoperative recovery. The aim of this editorial was to perform a r...

A Method for Gradient Calibration in Diffusion Weighted Imaging

Introduction. Conventional gradient calibration procedures do not exclude significant bias in the diffusion-weighted (DW) signal during MR experiments. The error, arising from imperfections in the DW gradients, varies among the different gradient directions and exhibits different extent of offsets. We propose a calibration method for DW imaging using a homogeneous water phantom, presuming that ...

Can CMR be the new ‘gold standard’ for constrictive pericarditis?

Historically, the cardiac catheterization has been the ‘gold standard’for the evaluation and confirmation of constrictive pericarditis. Noninvasive CMR should have a potential role to be equivalent or even superior given its abiltiy to detect both the anatomic and physiologic impact of an abnormal pericardium. Via RF tissue-tagging, we show that CMR could be a contender for a new non-invasive s...

A Method for Defuzzication by Weighted Distance

diffusion weighted imaging in acute attacks of multiple sclerosis

conclusion these data indicate that while ce-mri will depict more positive results, there are cases in which dwi will show a positive result while ce-mri is negative. we suggest that the combination of these two imaging modalities might yield more positive results in diagnosing acute ms attack giving rise to a more accurate diagnosis. results ce-mri yielded positive results for 61 (87%) patient...
