COVID-19 during pregnancy: non-reassuring fetal heart rate, placental pathology and coagulopathy.

We report a case of a pregnant woman with COVID-19 who developed coagulopathy in the absence of severe clinical symptoms. A polymerase chain reaction test of a vaginal swab was positive for SARS-CoV-2 RNA, suggesting a possibility of perinatal transmission. Cesarean delivery was performed because of a non-reassuring fetal heart rate; the placenta showed increased perivillous fibrin deposition and intervillositis.

Evaluation of various apparent diffusion coefficient measurement techniques in pre-operative staging of early cervical carcinoma.

Purpose: DW-MRI parameters such as ADC hold the potential for more reliable staging of cervical cancer. We compared 2D region of interest (ROI) measurement techniques to 3D tumor analysis in the evaluation of ADC for cervical cancer. Secondly, we evaluated the utility of ADC for assessing parametrial and/or lymph node involvement.

Assessment of parametrial invasion of cervical carcinoma, the role of T2-weighted MRI and diffusion weighted imaging with or without fusion.

Aim: To evaluate the diagnostic performance of diffusion-weighted imaging (DWI), with and without fusion images, in addition to regular T2-weighted (T2W) sequences for assessment of parametrial invasion.

Materials And Methods: This prospective cohort included cervical cancer patients who underwent preoperative magnetic resonance imaging (MRI) with T2W and axial DWI sequences prior to radical hysterectomy. Retrospectively, two radiologists independently and blindly scored the likelihood of parametrial invasion by means of a six-point confidence scale.

Positron emission tomography-magnetic resonance imaging (PET-MRI) for response assessment after radiation therapy of cervical carcinoma: a pilot study.

Background: Advanced stage cervical cancer is primarily treated by radiotherapy. Local tumor control is a prerequisite for cure. Imaging after treatment is controversial.
