The sagittal diameter of the cervical spinal canal is traditionally evaluated when an expansile intraspinal lesion is suspected. Some workers have concluded that the normal sagittal diameter gradually decreases from C1 to C7 in some peop... DK Yousefzadeh,GY El-Khoury,WL Smith - 《Radiology》 被引...
Retrospective analysis was performed on the MDCT and MRI scans. A total of 14 midsagittal parameters and 2 coronal parameters were investigated. The data were analysed statistically. Results: C.T. for PAI, BAI, BDI, OPFD, and OPFB: there were statistically significant diffe...
To evaluate the differences between target and normal tissue delineation between magnetic resonance imaging (MRI) and computed tomography (CT) in cervical cancer patients and to explore the differences in dosimetry after brachytherapy planning.High-dose-rate brachytherapy was performed on 11 patients. Pla...
(B) Sagittal reformatted CT image shows the RV, pulmonary outflow tract, and main pulmonary artery (MPA) forming the anterior contour of the heart. AA, Aortic arch; LPA, left pulmonary artery. Diaphragm On a chest radiograph the upper surface of the dome-shaped diaphragm is normally ...
It is not always possible to achieve a precise sagittal position of the head. Even a slight tilt ( Fig. 34.1 ) will make the temporal lobe (110) appear on one side, whereas on the other side the mastoid cells (62) can be seen. Fig. 34.1a Fig. 34.1b Fig. 34.1c Fig. 34.2a Fig...
These structures were more easily observed in sagittal or coronal sections than in transaxial sections. All were delineated by PET, whereas 4 were missed by MRI. Thirteen and 7 cervical coregistered well, with a center-of-mass distance of <2 mm, whereas 10 lymph node metastases were slightly...
Sagittal and axial gadolinium enhanced (gad-) T1w images (FSE, TE = 5.5 ms, TR = 500 ms, 12 averages, rare factor = 4, FOV = 40 × 40 mm, pixel size = 0.2 × 0.2 mm, slice thickness = 0.5 mm), taken on a 7 T preclinical MRI scanner ...
Craniocervical relationship in dorsal-ventral dimension was evaluated by the ratio between BD and OV on a midsagittal PMCT image of the cervical region modified from Powerset al.22. The reconstructed midsagittal PMCT image was chosen as the single image with best alignment of the mesorostral groo...
Fig. 3. Brain magnetic resonance imaging (MRI) findings in the patient at age 4 years: T2 axial (left, middle) and T1 sagittal (right) reveals white matter hyper-intensities of the peritrigonal and periventricular region adjacent to the right lateral ventricle. At age 4 years, the patient ...
