Feasibility, Safety and Impact of (18F)-FDG PET/CT in patients with pregnancy-associated cancer: experience of the French CALG (Cancer Associé à La Grossesse) network.

Background: The incidence of pregnancy-associated cancers has been increasing for decades. (18F)-FDG Positron Emission Tomography (PET)/Computed Tomography (CT) imaging has become a golden standard in the staging of many malignant diseases. The aims of the current study were to evaluate the feasibility, safety and impact of (18F)-FDG PET/CT performed during pregnancy.

[Cesarean scare niche: Definition, diagnosis, risk factors, prevention, symptoms, adverse effects, and treatments].

Objectives: To review the definitions, diagnostic methods, risk factors, symptoms, and treatments for caesarean scar niche.

Methods: Review of the literature, critical reflection, and pragmatic advice.

Results: There is no consensus on the definition of caesarean scar niche.

[Impact of the menstrual cycle on the quality of interpretation of the MRI result in the follow-up of women at genetic risk for breast].

Introduction: Breast MRI is used as a reference for screening breast cancer among women with a genetic high risk. Its sensitivity and specificity might decrease because of the background parenchymal enhancement. Therefore, it is recommended to plan the MRI between the 7th and the 14th day of the menstrual cycle despite of the burden of this organization.

Breast tomosynthesis: What do we know and where do we stand?

Digital breast tomosynthesis (DBT) is a new imaging technology that addresses the limitation caused by overlapping structures in conventional two-dimensional digital mammography owing to the acquisition of a series of low-dose projection images. This unique technique provides a dual benefit to patients screened for breast cancer. First, DBT increases the cancer detection rate mostly by highlighting architectural distortions and allowing better assessment of masses shape and margins.

Characterization of small (<4cm) solid renal masses by computed tomography and magnetic resonance imaging: Current evidence and further development.

Diagnosis of renal cell carcinomas (RCC) subtypes on computed tomography (CT) and magnetic resonance imaging (MRI) is clinically important. There is increased evidence that confident imaging diagnosis is now possible while standardization of the protocols is still required. Fat-poor angiomyolipoma show homogeneously increased unenhanced attenuation, homogeneously low signal on T2-weighted MRI and apparent diffusion coefficient (ADC) map, may contain microscopic fat and are classically avidly enhancing.
