Detection and evaluation of pelvic lymph nodes in patients with gynecologic malignancies using body diffusion-weighted magnetic resonance imaging.
In this study, the potential in detecting and evaluating pelvic lymph node metastases on body diffusion-weighted (DW) images was evaluated in patients with gynecologic malignancies. ⋯ Body DW images are useful in detection of pelvic lymph nodes in patients with gynecologic malignancy. However, the measurement of ADC values does not contribute to a diagnosis of metastatic nodes.

Comparative StudyLiver lesion detection and characterization in patients with colorectal cancer: a comparison of low radiation dose non-enhanced PET/CT, contrast-enhanced PET/CT, and liver MRI.
To compare low-radiation dose non-enhanced fluorine 18 fluorodeoxyglucose (F-18 FDG) positron emission tomography (PET)/computed tomography (CT) (NE-PET/CT), contrast-enhanced fluorine 18 fluorodeoxyglucose PET/CT (CE-PET/CT), and gadolinium-enhanced liver magnetic resonance imaging (MRI) for the detection and characterization of liver lesions in patients with colorectal cancer (CRC). ⋯ When performing PET/CT, optimal detection and characterization of liver lesions require the use of a fused contrast-enhanced CT. Magnetic resonance imaging and CE-PET/CT have similar lesion detection rates. Magnetic resonance imaging is the best test for liver lesion characterization in patients with CRC.
