The uterine unfolding sign: A sonographic marker in cesarean scar pregnancy beyond the first trimester.

Cesarean scar pregnancy refers to the complete or partial implantation of a gestational sac within an existent cesarean scar. Expectant management of caesarean scar pregnancy can lead to uterine rupture, a rare but life-threatening complication. We report here a sonographic marker which could predict short-term risk of uterine rupture in the context of expectant management of CSP after 15 weeks.

CT imaging findings of invasive pulmonary fungal infections in hemato-oncologic children.

Hemato-oncologic children form a heterogeneous group with a wide spectrum of ages, malignancy types, and immunosuppression grades during the different phases of their treatment. Immunosuppression is caused by multiple factors, including the malignancy itself, bone marrow suppression secondary to therapy, and wide use of steroids and antibiotics, among others. At the same time, the risk of infections in these patients remains high because of prolonged hospitalizations or the need for long-timing implanted devices between other features.

Development of a user-friendly calculator for a pediatric split-bolus polytrauma computed tomography protocol.

We present here a user-friendly calculator for the setting of a pediatric split-bolus polytrauma computed tomography (CT) protocol with a mixed arterial and venous phase, aiming to both reduce radiation dose and improve workflow while assuring optimal image quality. All the different parameters are calculated based on patient's weight with rapid computation of the injected contrast media and saline volumes, injection's flow rate, injection's timing, and optimal acquisition time. The designed calculator is built in a widely available Google Sheets file, accessible by a quick response (QR) code.

Gated cardiac CT in infants: What can we expect from deep learning image reconstruction algorithm?

Background: ECG-gated cardiac CT is now widely used in infants with congenital heart disease (CHD). Deep Learning Image Reconstruction (DLIR) could improve image quality while minimizing the radiation dose.

Objectives: To define the potential dose reduction using DLIR with an anthropomorphic phantom.

Prenatal magnetic resonance imaging of complex female genitourinary system abnormalities, what the fetal medicine specialist needs to know.

Complex female genitourinary system anomalies include a wide spectrum of uncommon pathologies, caused from the abnormal separation of the urorectal septum and the urogenital sinus in early embryonic life. The resulting fusion of the distal urinary, genital and intestinal tracts increases the risk of death in utero and alters the normal organ functionality and the quality of life in survivors. An accurate prenatal identification of these pathologies depends mainly on prior suspicion at ultrasound screening, but also requires a solid knowledge of embryology and familiarity with the different patterns of malformation.
