Acromioclavicular joint tuberculosis: A report of two cases.

Acromioclavicular joint tuberculosis is an extremely rare presentation with only 16 cases reported so far and has a relatively high propensity to be misdiagnosed. India being a tuberculosis endemic region accounts for almost 27% of cases worldwide (global index of 2018 was 10 million). With a higher index of suspicion an earlier diagnosis can be made.

Ectopic Immature Renal Tissue Associated with Lipomeningomyelocele and Enteric Duplication Cyst: A Report of Two Cases.

Ectopic immature renal tissue (EIRT) is a lesion rarely described in the literature. It shows the components of a nephrogenic rest including the blastema, epithelia, and stroma. We report two cases of EIRT in a 3-year-old female and an 8 months male child, associated with lipomeningomyelocele and an enteric duplication cyst, respectively, along with detailed immunohistochemical profile.

Advanced neuroimaging to guide acute stroke therapy.

Traditionally non-contrast CT has been considered the first choice imaging modality for acute stroke. Acute ischemic stroke patients presenting to the hospital within 3-hours from symptom onset and without any visible hemorrhages or large lesions on CT images are considered optimum reperfusion therapy candidates. However, non-contrast CT alone has been unable to identify best reperfusion therapy candidates outside this window.

Time-resolved MR angiography of the legs at 3 T using a low dose of gadolinium: initial experience and contrast dynamics.

Objective: This article describes our initial clinical experience with time-resolved MR angiography (MRA) of the legs using the time-resolved imaging with stochastic trajectories (TWIST) technique with a half dose of gadolinium.

Materials And Methods: Thirty-four patients underwent a TWIST examination of the legs at 3 T. Thirty-three patients also underwent a bolus-chase MRA examination in the same setting.

Whole animal imaging.

Translational research plays a vital role in understanding the underlying pathophysiology of human diseases, and hence development of new diagnostic and therapeutic options for their management. After creating an animal disease model, pathophysiologic changes and effects of a therapeutic intervention on them are often evaluated on the animals using immunohistologic or imaging techniques. In contrast to the immunohistologic techniques, the imaging techniques are noninvasive and hence can be used to investigate the whole animal, oftentimes in a single exam which provides opportunities to perform longitudinal studies and dynamic imaging of the same subject, and hence minimizes the experimental variability, requirement for the number of animals, and the time to perform a given experiment.
