CT Colonographic Screening of Patients With a Family History of Colorectal Cancer: Comparison With Adults at Average Risk and Implications for Guidelines.

Objective: The purposes of this study were to compare rates of lesion detection at CT colonographic (CTC) screening of adults without symptoms who had and who did not have a family history of colorectal cancer according to American Cancer Society guidelines and to consider the clinical implications.

Materials And Methods: Over 134 months, consecutively registered CTC cohorts of adults without symptoms who had (n = 156; 88 [56.4%] women; 68 [43.

Prospective Evaluation of Reduced Dose Computed Tomography for the Detection of Low-Contrast Liver Lesions: Direct Comparison with Concurrent Standard Dose Imaging.

Objectives: To prospectively compare the diagnostic performance of reduced-dose (RD) contrast-enhanced CT (CECT) with standard-dose (SD) CECT for detection of low-contrast liver lesions.

Methods: Seventy adults with non-liver primary malignancies underwent abdominal SD-CECT immediately followed by RD-CECT, aggressively targeted at 60-70 % dose reduction. SD series were reconstructed using FBP.

Percutaneous Microwave Ablation of an Insulinoma in a Patient with Refractory Symptomatic Hypoglycemia.

Insulinomas are the most common functioning pancreatic neuroendocrine tumors (pNETs). Surgical excision is the preferred therapy, and medical treatment with diazoxide or octreotide is typically reserved for those who are poor surgical candidates. A recent emergence of minimally invasive treatment modalities has led to reports of successful radiofrequency and ethanol ablation of insulinomas.
