In conclusion : MRI is- superior to CT to demonstrate the anatomy of the pituitary gland. The patient with the isolated DI, with variation in polyuria, shows no identifiable antehypophyseal tissue. It is our opinion that PESS in children as defined by CT scan, groups heteroqenous anatomical ...
CostMRI costs range from $1,200 to $4,000 (with contrast), which is usually more expensive thanCT scansand X-rays, and most examining methods.X-Ray is relatively cheaper than MRI (~70$ on average) Time taken for complete scanDepending on what the MRI is looking for, and where it is...
Positron emission tomography / computed tomography (PET/CT), with its metabolic data of 18F-fluorodeoxyglucose (FDG) cellular uptake in addition to morphologic CT data, is an established technique for staging of lung cancer and has higher sensitivity and accuracy for lung nodule characterization than...
Gd-EOB-DTPA具有非特异性细胞外对比剂和肝胆特异性对比剂的双重特征,能够同时提供似常规三期动态增强和HBP图像[9]。Gd-EOB-DTPA动态增强MRI较动态增强CT、超声造影、PET/CT等其他影像学检查更有优势,尤其对于微小病灶的准确度更高[...

CT scan has been used for preoperative evaluation on AVC tumors. Barbosaet al.19reported an accuracy of 75% of spiral CT scan for AVC tumors. suggesting an important role CT played in T staging. However, Hartet al.20reported that spiral CT scan could not precisely reveal the invasion of ...
Comparative Effectiveness of 18F-FDG PET/CT Versus Whole-Body MRI for Detection of Malignant Peripheral Nerve Sheath Tumors in Neurofibromatosis Type 1 fused 18F FDG-PET and MRI (PET/MRI fusion image) in diagnosing pancreatic tumor, in particular differentiating malignant tumor from benign lesions. ...
This chapter summarizes the findings of a global survey aimed at assessing the strengths, weaknesses, opportunities, and threats (so-called SWOT analysis) of hybrid imaging (HI). Hybrid imaging comprises three imaging modalities: single-photon emission t
Wu and associates (2018) noted that use of MRI for cervical clearance after a negative cervical CT scan result in alert patients with blunt trauma who are neurologically intact is not infrequent, despite poor evidence in regard to its utility. These investigators evaluated the utility and cost-ef...
The purpose of this study was to compare the ability of 18F-FDG PET/CT and contrast-enhanced MRI (CEMRI) to detect and grade venous tumour thrombus (VTT) and venous bland thrombus (VBT) in RCC and assess invasion of the venous wall by VTT. The PET/CT and
