Intra-osseous migration in calcific rotator cuff tendinopathy- a novel depiction of temporal evolution on multimodality imaging.

We present a case of calcific tendinopathy of the rotator cuff with intraosseous migration of the calcification, treated with ultrasound-guided bursal steroid injection and followed up with multiple imaging modalities for a year following the initial presentation. The radiographs, ultrasound, CT, nuclear scintigraphy, and MRI images demonstrate the temporal evolution of the intraosseous migrated calcium and show how this pathology, in its acute phase, can mimic other pathologies like osteoid osteoma. The follow-up imaging also illustrates how the migrated intraosseous focus of calcification took a much longer time to heal compared to its intratendinous counterpart, possibly leading to the protracted course of recovery.

Accuracy of Whole-Body DWI for Metastases Screening in a Diverse Group of Malignancies: Comparison With Conventional Cross-Sectional Imaging and Nuclear Scintigraphy.

Objective: The purpose of this study is to assess the role of whole-body (WB) DWI as a screening modality for the detection of metastases and to compare it to conventional cross-sectional imaging modalities or nuclear scintigraphy in a population with various histopathologic malignancies.

Subjects And Methods: WB DWI and conventional imaging (CT, MRI, or scintigraphy) were performed for patients with known malignancies for metastatic workup, and these patients were followed up for a period of 1 year. Two radiologists assessed WB DW images separately, and conventional images were assessed by the senior radiologist.

Efficacy of Perfusion Computed Tomography (PCT) in Differentiating High-Grade Gliomas from Low Grade Gliomas, Lymphomas, Metastases and Abscess.

Introduction: Tumoural angioneogenesis and its quantification are important in predicting the tumour grade and in the management with respect to the treatment available and to assess the response to treatment and the prognosis. It also plays major role in the growth and spread of tumours. Hence, a need arises for non-invasive in vivo methods to assess tumour angioneogenesis and tumour grade at the time of presentation and for monitoring the response during treatment and follow up.
