Heterotopic twin pregnancy in unicornuate uterus and non-communicating rudimentary horn with survival of both fetuses: Magnetic resonance imaging and 3D reconstructions findings.

We reported a case of heterotopic twin pregnancy in a unicornuate uterus with a non-communicating rudimentary horn with survival of both fetuses. The diagnosis was made late at 28 weeks of gestation, with suspicion raised by ultrasound and confirmed by magnetic resonance imaging (MRI). During hospitalization, obstetric ultrasound with color Doppler was performed every 2 days to assess fetal well-being and myometrial thickness, which was determined by measurements of the uterine wall at the accessory horn.

Clinical usefulness of tissue acquisition of pancreatic cystic lesions using an endoscopic ultrasound-guided needle for histological analysis.

There are rare data on the usefulness of endosonography-guided tissue acquisition (EUS-TA) in patients with pancreatic cystic lesions (PCLs). This study aimed to determine the accuracy of EUS-TA with ProCore 20G (PC20) for differentiating between mucinous neoplasia (MN) and non-MNs (n-MN) and identifying malignant PCLs, as well as its adverse events (AEs) in patients with PCLs without a classificatory diagnosis by imaging exams. In this observational, retrospective, single-center study, all patients with PCL who underwent EUS-TA due to diagnostic doubts in imaging studies were consecutively recruited from June 2017 to December 2021.

Lumbosacral plexus MR tractography: A novel diagnostic tool for extraspinal sciatica and pudendal neuralgia?

Background: Diagnosing extraspinal sciatica and pudendal neuralgia remains a clinical challenge. MRI and MR Neurography (MRN) are currently the standard techniques used to support the diagnosis of extraspinal lumbosacral plexus entrapments; however, for the intrapelvic portions of the lumbosacral plexus their accuracy is still limited. MR Tractography (MRT) feasibility to image the lumbosacral plexus has been demosntrated, but its clinical applications have yet to be determined.

Analysis of risk factors associated with acute pancreatitis after endoscopic papillectomy.

Acute pancreatitis (AP) is a common adverse event (AE) of endoscopic papillectomy (EP). Prophylactic plastic pancreatic stent (PPS) placement appears to prevent AP. We evaluated factors associated with post-EP AP by a retrospective analysis of patients with tumors of the duodenal papilla who underwent EP from January 2008 to November 2016 at 2 tertiary care centers.

Impact of uterine contractility on quality of life of women undergoing uterine fibroid embolization.

MAGNETIC RESONANCE CHOLANGIOPANCREATOGRAPHY (MRCP) VERSUS ENDOSONOGRAPHY-GUIDED FINE NEEDLE ASPIRATION (EUS-FNA) FOR DIAGNOSIS AND FOLLOW-UP OF PANCREATIC INTRADUCTAL PAPILLARY MUCINOUS NEOPLASMS.

Background: Intraductal papillary mucinous tumor (IPMN) are being diagnosed with increasing frequency. Computerized tomography scanning is commonly used as the primary imaging modality before surgery nonetheless magnetic resonance cholangiopancreatography (MRCP) provides better characterization. Endosonography-guided fine needle aspiration (EUS-FNA) has emerged as a way to reach pathological diagnose.

Functional magnetic resonance imaging for clinical evaluation of uterine contractility.

Uterine contractility out of the gestational phase, during the menstrual cycle and the habitual functional variations of the organ, this is one of the responsible mechanisms for reproduction and fertility, due to its direct action in the mechanisms conducting the spermatozoa to the ovule and in the decidual implantation. Pathologies such as uterine leiomyoma, endometriosis, adenomyosis, polycystic ovarian syndrome, as well as the use of intrauterine devices and oral contraceptives, may alter a functionality of uterine contractility. Thus, magnetic resonance imaging with ultrafast sequences provides a dynamic evaluation (cine-MRI) and thus the correlation of uterine contractility quality in patients with current infertility or pathologies.

Interventional radiology and endovascular surgery in the treatment of ectopic pregnancies.

The advent of interventional radiology enabled remarkable advances in diagnosis and treatment of several situations in obstetrics and gynecology. In the field of obstetrics, these advances include temporary occlusion of the iliac arteries to the management of placenta accreta and/or prior, arteriovenous fistulas after embolization of uterine curettage and management of ectopic uterine and extra-uterine pregnancies. The non-tubal ectopic pregnancy, either cervical, abdominal, ovarian or in a cesarean scar, often represents major therapeutic challenge, especially when exists a desire to maintain fertility.

Prevalence of incidental pancreatic cysts on 3 tesla magnetic resonance.

Objectives: To ascertain the prevalence of pancreatic cysts detected incidentally on 3-Tesla magnetic resonance imaging (MRI) of the abdomen and correlate this prevalence with patient age and gender; assess the number, location, and size of these lesions, as well as features suspicious for malignancy; and determine the prevalence of incidentally detected dilatation of the main pancreatic duct (MPD).
