A novel ultrasound scanning approach for evaluating femoral cartilage defects of the knee: comparison with routine magnetic resonance imaging

This study aimed to assess a novel ultrasound (US) scanning approach in evaluating knee femoral cartilaginous defects, compared with magnetic resonance imaging (MRI, commonly used for knee imaging) and arthros...

Duplex ultrasound examination, computed tomography scans, and magnetic resonance angiography have traditionally been used as noninvasive methods to assess carotid stenosis severity. The degree of stenosis in asymptomatic patients has often been used as the main criterion to assess risk for plaque embolization and stroke. There has been an effort to find alternate methods to assess vulnerable plaques. This has included many modalities, including magnetic resonance imaging and other ultrasound techniques.

Study Design. A prospective, observational cohort study. Objective. The aim of this study was to determine the role of pre and postvoid bladder scan in predicting cauda equina syndrome (CES). The thesis was that bladder scanning [specifically postvoid residual (PVR) volume] would have higher diagnostic accuracy than physical examination alone. Summary of Background Data. CES is an ill-defined condition with a spectrum of presenting symptoms. There is neither a combination of clinical symptoms and/or signs that reliably predicts cauda equina compression nor single defining clinical criterion that has 100% predictive...

Authors: Tomicic V, Cornejo R Abstract In recent years there has been substantial progress in the imaging evaluation of patients with lung disease requiring mechanical ventilatory assistance. This has been demonstrated by the inclusion of pulmonary ultrasound, positron emission tomography, electrical impedance tomography (EIT), and magnetic resonance imaging (MRI). The EIT uses electric current to evaluate the distribution of alternating current conductivity within the thoracic cavity. The advantage of the latter is that it is non-invasive, bedside radiation-free functional imaging modality for continuous monitorin...

The purpose of this study was to assess the similarity of free Achilles tendon shape and 3-D geometry between magnetic resonance imaging (MRI) and freehand 3-D ultrasound (3-DUS) imaging methods. Fourteen elite/sub-elite middle-distance runners participated in the study. MRI and 3-DUS scans of the Achilles tendon were acquired on two separate imaging sessions, and all 3-D reconstructions were performed using identical methods. Shape similarity of free Achilles tendon reconstructed from MRI and 3-DUS data was assessed using Jaccard index, Hausdorff distance and root mean square error (RMSE).

ReinholdAbstractUterine leiomyomas, the most frequent benign myomatous tumors of the uterus, often cannot be distinguished from malignant uterine leiomyosarcomas using clinical criteria. Furthermore, imaging differentiation between both entities is frequently challenging due to their potential overlapping features. Because a suspected leiomyoma is often managed conservatively or with minimally invasive treatments, the misdiagno...

AbstractPurpose of ReviewFor uterine cervical cancer, the recently revised International Federation of Gynecology and Obstetrics (FIGO) staging system (2018) incorporates imaging and pathology assessments in its staging. In this review we summarize the reported staging performances of conventional and novel imaging methods and provide an overview of promising novel imaging methods relevant for cervical cancer patient care.Recent FindingsDiagnostic imaging during the primary diagnostic work-up is recommended to better assess tumor extent and metastatic disease and is now reflected in the 2018 FIGO stages 3C1 and 3C2 (positi...

CONCLUSION: The requirements of imaging are determined by clinical presentation, laboratory findings, tumor stage, the presence of a tumor syndrome and the need of a personalized systemic treatment modality. PMID: 31359091 [PubMed - as supplied by publisher]

By now most of us are familiar with Brexit, the UK’s pending divorce with the European Union. But in a play on that term, British doctors are also moving towards an exit they’ve dubbed “TRexit” from the most common sort of prostate biopsy: the transrectal ultrasound guided biopsy, or TRUS. Men who test positive on the PSA cancer screening test will usually have a prostate biopsy that’s performed in either of two ways. With a TRUS, doctors guided by an ultrasound machine can sample the prostate using a biopsy needle inserted through the rectum. Alternatively, the biopsy needle can be inserted (...

Jnl Wrist Surg DOI: 10.1055/s-0039-1693147 Background Scaphoid fracture accounts for approximately 15% of acute wrist fractures. Clinical examination and plain X-rays are commonly used to diagnose the fracture, but this approach may miss up to 16% of fractures in the absence of clear-cut lucent lines on plain radiographs. As such, additional imaging may be required. It is not clear which imaging modality is the best. The goal of this study is to summarize the current literature on scaphoid fractures to evaluate the sensitivity, specificity, and accuracy of four different imaging modalities.
