The purpose was to compare contrast-enhanced PET/CT (cePET/CT) and non contrast-enhanced PET/MRI (PET/MRI) concerning diagnostic accuracy in evaluation of abdominal lesions. METHOD AND MATERIALS 21 patients (mean age 59.5 years, range 35 to 78 years, 11 female, 10 male) with suspected ...
Generally, greater head involvement was depicted by contrast compared with non-contrast MRI (Pearson r = 0.37, P = 0.04). Conclusion Pre- and postcontrast MRI assess two different components of stage I LCP. However, contrast-enhanced MRI more clearly depicts the area of involvement. 展开 ...

Dynamic contrast-enhanced MRI in advanced nonsmall-cell lung cancer patients treated with first-line bevacizumab, gemcitabine, and cisplatin Purpose:To investigate dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) of advanced nonsmall-cell lung cancer (NSCLC) patients treated with... MD...
Objective To compare the clinical outcomes of patients selected for mechanical thrombectomy by noncontrast computed tomography (CT) vs those selected by computed tomography perfusion (CTP) or magnetic resonance imaging (MRI) in the extended time window. Design, Setting, and Participants This multinationa...

interval progression, defined by as at least one new or unequivocally enlarged lesion on follow-up MRI scans. There were a total of 1,992 new or enlarged lesions. With 3T MRI, the assessment of interval progression did not differ significantly between the contrast-enhanced and non-enhanced ...
Are non-ionic gadolinium contrast agents better than ionic ones? Not necessarily. An analogy is often made to the well-recognized superiority of nonionic iodine-based contrast agents over ionic ones in terms of renal safety and adverse reactions. The (false) conclusion is that non-ionic ...
Magnetic Resonance Imaging (MRI) is a non-invasive versatile tool for achieving full-field quantitative visualization. The MRI signal is a result of the interaction between radiofrequency (RF) pulses with nuclear spins exposed to a strong static magnetic field. The two main classes of techniques ...
