Accuracy of Chest Computed Tomography in Distinguishing Cystic Pleuropulmonary Blastoma From Benign Congenital Lung Malformations in Children.

Importance: The ability of computed tomography (CT) to distinguish between benign congenital lung malformations and malignant cystic pleuropulmonary blastomas (PPBs) is unclear.

Objective: To assess whether chest CT can detect malignant tumors among postnatally detected lung lesions in children.

Design, Setting, And Participants: This retrospective multicenter case-control study used a consortium database of 521 pathologically confirmed primary lung lesions from January 1, 2009, through December 31, 2015, to assess diagnostic accuracy.

Birth-related subdural hemorrhage: prevalence and imaging morphology.

Background: Birth trauma accounts for 1-2% of the mortality in newborns with significant intracranial injuries presenting in the immediate postnatal period. However, a significant number of asymptomatic neonates harbor birth-related intracranial hemorrhage (ICH), with birth-related subdural hemorrhage (SDH) being a common occurrence on infant brain CT and MRI studies performed as a standard of care for a variety of reasons. Although clinically insignificant, birth-related SDH is frequently brought up in courts as an alternative explanation for SDH in suspected abusive head trauma.

Clinical utilization of whole-body PET/MRI in childhood sarcoma.

Hybrid positron emission tomography (PET)/magnetic resonance imaging (MRI) has emerged as a useful tool that combines the superior tissue contrast of MRI with the targeted functional imaging of PET. In the assessment of sarcomas in children, PET/MRI has the potential to serve as a single point of service, allowing superior anatomical imaging and evaluation of metabolic uptake during one imaging session. In this pictorial essay, we review our preliminary experience with PET/MRI in the evaluation of pediatric sarcoma.

Normal FDG uptake in the adenoids and palatine tonsils in children on PET/MRI.

Background: Information about the normal [F-18]2-fluoro-2-deoxyglucose (FDG) uptake in the adenoids and palatine tonsils in children is not available.

Objective: The purpose of this study was to report the range of standardized uptake values (SUVs) in the normal adenoids and palatine tonsils in children, assess for the degree of asymmetry between the right and left tonsils and evaluate for the correlation of SUVs between the adenoids and tonsils.

Materials And Methods: Pediatric patients who had had an FDG positron emission tomography (PET)/magnetic resonance imaging (MRI) brain study in our institution from January 2018 to March 2019 were identified.

E-cigarette, or vaping, product use-associated lung injury in adolescents: a review of imaging features.

Background: There has been a recent increase in recognition of lung disease related to the use of electronic cigarettes (called "vaping"). These patients present with acute respiratory illness following exposure to vaporized cannabis or nicotine products and sometimes require hospitalization and intensive care. We describe the imaging findings of this disease entity in the pediatric population.

Complications of percutaneous gastrostomy and gastrojejunostomy tubes in children.

Percutaneous feeding tubes are generally considered a safe option for enteral feeding and are widely used in children who require long-term nutritional support. However, complications are not infrequent and can range from bothersome to life-threatening. Radiologists should be familiar with the imaging appearances of potential complications for optimal patient care.

Fluoroscopic Diagnosis of Malrotation: Technique, Challenges, and Trouble Shooting.

A fluoroscopic upper gastrointestinal series is the most commonly used investigation for the diagnosis of malrotation and midgut volvulus. However, both false positive and false negative results can occur causing diagnostic confusion. Several physiologic states and pathologic conditions can mimic fluoroscopic appearance of malrotation.

Ambiguous Findings on Radiographs.

Findings with uncertain clinical significance are frequently encountered on radiographs. A structure or opacity visible on radiographs could be due to several causes ranging from artifact or external structure to malignancy or a life-threatening process. The approach that a radiologist chooses to address ambiguous findings can have a significant impact on a patient's health.

Spontaneous Intracranial Hypotension With Site of Leak Detected Only After 111In-DTPA Cisternogram.

A 54-year-old man with a 3-week history of orthostatic headache and acute on chronic subdural hematoma presented with imaging findings suggestive of spontaneous intracranial hypotension. Three myelograms were negative for leak, and nontargeted epidural blood patches did not result in symptom relief. A cerebrospinal fluid leak study using In-DTPA with SPECT/CT demonstrated a focal area of asymmetric activity at the left C2 nerve root.

Why Thyroid Surgeons Are Frustrated with Radiologists: Lessons Learned from Pre- and Postoperative US.

Optimal treatment of thyroid cancer is highly dependent on accurate staging of the extent of disease at presentation. Preoperative ultrasonography (US) is the most sensitive method for detecting metastatic lymph nodes and is recommended as part of the standard preoperative workup. Missed findings on preoperative scans may lead to understaging and inadequate surgical management, which subsequently predispose these patients to residual disease postoperatively and a higher risk for recurrence, possibly requiring repeat surgery.

Role of diffusion-weighted MRI in acute pyelonephritis: a prospective study.

Background: Imaging is vital in diagnosis of complicated pyelonephritis and has been traditionally performed by computed tomography (CT). However, CT with contrast agents cannot be performed in patients with renal failure. Diffusion-weighted (DW) magnetic resonance imaging (MRI) has the potential to overcome this disadvantage.
