evaluation of a patient with signs or symptoms of spinal stenosis, where MRI or CT are equally appropriate. For evaluation of recurrent symptoms after spinal surgery, MRI with and without gadolinium enhancement, is the preferred method of imaging. Magnetic resonance imaging or CT evaluation of chron...
At least three dedicated, cable-bound sur- face coils have been developed to overcome the low filling factor of dental MRI with conventional head- and neck imaging coils10,15,18, one of which is commercially available (4-channel dental-array, Noras MRI Products GmbH, Höchberg, Germany)35....

Experimental setup. (a) Diagram showing the 30 cm diameter hemisphere phased array with a coronal MRI of the rat head superimposed. The top of the head was partially submerged. A passive cavitation detector was placed near the bottom of the array. The geometric focus (green+) was approximat...
If the clinical utility of 18F-FDOPA PET/CT and/or PET/MRI is confirmed, GTVPET/MRI should be considered for tailored radiotherapy planning in patients with SBPGL. Keywords: paraganglioma; head and neck; radiotherapy; 18F-FDOPA; PET; GTV Cancers 2019, 11, 54; doi:10.3390/cancers11010054 ...
However, one of the known advantages of convolutional neural networks (CNN) is that the pre-processing and the feature engineering do not have to be performed. The aim of this research is firstly to examine the classification of three tumor types from an imbalanced database with a CNN. ...
A theranostic approach, through which imaging companions are integrated with SeNPs, will allow image-guided drug delivery and, therefore, is highly desirable. Traditional methods require the chemical conjugation of imaging agents to the surface of nanoparticles, which may impede the later clinical ...
High-power RF phase shifters and RF attenuators were used to adjust the phase and the power attenuation at the ports, respectively. A practical design of a four-port elliptical high-pass birdcage with asymmetric leg distribution was adopted for narrow-bore MRI (magnet bore inner diameter, 64 ...
Abbreviated protocols are supposed to improve the cost-effectiveness of breast MRI, particularly in populations that are not at high risk of breast cancer and in health care systems with conservative WTP-thresholds. Recently, the first prospective head-to-head comparison of DBT and AB-MRI for ...
