MRI without contrast of at least 1.5 T, with a radiologist report, was used as a criterion for the detection of long head of the biceps injury. All cases were operated by the same surgeon at this hospital. This study evaluated data from 965 patients, 311 women (32%) and 654 men (...
The detection of acute blood into the CSF (ventricles and subarachnoid spaces) with MRI is more complicated.The higher oxygen tension (pO2) in the CSF slows the transformation of oxyhemoglobin to paramagnetic breakdown products such as deoxyhemoglobin and methemoglobin. Traditional T1-W or T2-W ...
Motion artefacts caused by the patient’s body movements affect magnetic resonance imaging (MRI) accuracy. This study aimed to compare and evaluate the accuracy of motion artefacts correction using a conditional generative adversarial network (CGAN) with an autoencoder and U-net models. The training...
Radiotherapy-MRI Development Cooperative* Received: 12 October 2017 Accepted: 18 December 2017 Published: 13 February 2018 Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) has been correlated with prognosis in head and neck squamous cell carcinoma as well as with changes in normal ...
PVIBGT and magnesium screws can improve the blood supply of the femoral head via DCE-MRI evaluation. Two patients with poor incision healing received prompt treatment and subsequently recovered well. No adverse events, such as hip infection or deep vein thrombosis, were reported in the patients. ...
increased soft tissue contrast allowing improved diagnostic performance compared with MR imag[1] ing alone or PET/CT alone (diagnostic accuracy of 0.926 vs 0.836 and 0.847; P<.05, respectively).6A potential drawback of PET/MR imaging is the ...
Clinical assessments were performed at 4, 8 and 12 weeks after the end of treatment, then every three months for the first two years and semi-annually thereafter. Radiographic follow-up (CT, MRI or PET-CT) was performed 8–12 weeks after the end of treatment and then semi-annually....
A variety of imaging protocols may be used for the visualization of the different features. MRI provides excellent soft tissue contrast, and allows images to be produced in virtually any plane. The standard protocol usually starts with a T1-weighted axial localizer (short TR, short TE). So-cal...
As MRI is very susceptible to head motion during the scan (Friston et al., 1996), hoping for good quality data is often equivalent to hoping for data with low head motion. The importance of reducing head motion during data acquisition has been impressively documented in several studies ...
Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) has been correlated with prognosis in head and neck squamous cell carcinoma as well as with changes in normal tissues. These studies implement different software, either commercial or in-house, and different scan protocols. Thus, the gen...
