[Diagnostic imaging findings in COVID-19].

This is a review of diagnostic imaging findings in coronavirus disease-2019 (COVID-19). CT findings are frequently bilateral, multilobar and peripheral ground-glass opacities with vascular enlargements. Consolidations often appear during progression as well as crazy paving and reticulation.

Ga-PSMA-PET/CT in comparison with F-fluoride-PET/CT and whole-body MRI for the detection of bone metastases in patients with prostate cancer: a prospective diagnostic accuracy study.

Objectives: To determine the diagnostic accuracy of gallium prostate-specific membrane antigen (PSMA)-based positron emission tomography/computed tomography (PET/CT) in comparison with F-fluoride-based PET/CT (NaF-PET/CT) and whole-body magnetic resonance imaging (WB-MRI) for the detection of bone metastases in patients with prostate cancer.

Methods: Sixty patients with prostate cancer were included in the period May 2016 to June 2017. The participants underwent three scans (index tests) within 30 days: a NaF-PET/CT, a WB-MRI and a PSMA-PET/CT.

Diagnostic bone imaging in patients with prostate cancer: patient experience and acceptance of NaF-PET/CT, choline-PET/CT, whole-body MRI, and bone SPECT/CT.

Background Patient acceptance is an important factor when implementing imaging methods in clinical practice in line with availability, diagnostic accuracy, and cost-effectiveness. Purpose To investigate patient experience and acceptance regarding18F-sodium fluoride (NaF) positron emission tomography/computed tomography (PET/CT), 11 C-choline-PET/CT, whole-body magnetic resonance imaging (WB-MRI), and 99mTc-hydroxymethane diphosphonate (HDP) single photon emission/computed tomography (SPECT/CT). Material and Methods One hundred and forty-nine patients with prostate cancer filled in a questionnaire regarding their experience of the imaging procedures they had been undergoing as part of a diagnostic accuracy study.

A prospective study comparing whole-body skeletal X-ray survey with 18F-FDG-PET/CT, 18F-NaF-PET/CT and whole-body MRI in the detection of bone lesions in multiple myeloma patients.

Background: For decades, the most widely used imaging technique for myeloma bone lesions has been a whole-body skeletal X-ray survey (WBXR), but newer promising imaging techniques are evolving.

Purpose: To compare WBXR with the advanced imaging techniques 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT), 18F-sodium fluoride (NaF) PET/CT and whole-body magnetic resonance imaging (WB-MRI) in the detection of myeloma bone lesions.

Material And Methods: Fourteen patients with newly diagnosed multiple myeloma were prospectively enrolled.

Short-term immobilization and recovery affect skeletal muscle but not collagen tissue turnover in humans.

Not much is known about the effects of immobilization and subsequent recovery on tendon connective tissue. In the present study, healthy young men had their nondominant leg immobilized for a 2-wk period, followed by a recovery period of the same length. Immobilization resulted in a mean decrease of 6% (5,413 to 5,077 mm(2)) in cross-sectional area (CSA) of the triceps surae muscles and a mean decrease of 9% (261 to 238 N.

Effects of long-term immobilization and recovery on human triceps surae and collagen turnover in the Achilles tendon in patients with healing ankle fracture.

The aim of the present study was to analyze how human tendon connective tissue responds to an approximately 7-wk period of immobilization and a remobilization period of a similar length, in patients with unilateral ankle fracture, which is currently unknown. Calf muscle cross-sectional area (CSA) decreased by 15% (5,316 to 4,517 mm2) and strength by 54% (239 to 110 N.m) in the immobilized leg after 7 wk.
