Multiple Benign Metabolically Active Lesions on F-18 FDG PET/CT can Mimic Malignant Lesions

F 18 FDG PETCT detection for liver metastases

Dual-time-point F-18 FDG PET/CT imaging for differentiating the lymph nodes between malignant lymphoma and benign lesions

PURPOSE The purpose of the present study is to evaluate the clinical value of dual-time-point F-18 FDG PET/CT imaging to differentiate malignant lymphoma (ML) from benign lymph node (BLN). MATERIALS AND METHODS The subjects were 310 lymph nodes in 84 patients (195 ML lesions in 30 patients and 115 BLN in 54 patients associated with various etiologies.). F-18 FDG PET/CT scan was performed at 5...

Benign lesions that mimic cancer: Ovarian

As ovarian masses are common in both preand in postmenopausal age, a life time risk of up to 5-10% to undergo pelvic surgery has been reported [1]. However, the likelihood of malignancy in these lesions is extremely low. Imaging, particularly, US and MRI, have been integrated as diagnostic tools to better define indications for adequate surgery and to guide referral to specialized centers. Imag...

Bone lesions: benign and malignant.

Differentiation of benign and malignant breast lesions by apparent diffusion coefficient value in mass and non-mass lesions

Background: Diffusion-weighted imaging (DWI) is one of methods in evaluation of breast lesions. We aimed to investigate the apparent diffusion coefficient (ADC) values in breast tumors and their accuracy in differentiating benign versus malignant lesions. Methods: In this cross-sectional study, 72 patients with 88 breast lesions were investigated by 1.5-T breast MRI from 2015 to 2017 in Athari...
