A Multidisciplinary Assessment of Standard Low Dose Versus Ultra-low Dose Chest CT Scans for Pectus Excavatum Imaging.

Aim: Evaluation of ultra-low dose chest CT imaging for the assessment of pectus excavatum severity as determined by pediatric radiologists and pediatric surgeons using Haller (HI) and Correction indices (CI).

Methods: A single institution, prospective evaluation of patients being evaluated for pectus excavatum were scanned with a standard low-dose chest CT protocol (CARE) followed by a consecutive ultra-low dose CT scan (ULTRA). 3 surgeons and 4 radiologists were instructed to determine HI and CI in each series.

Preoperative ultrasound for the diagnosis of thyroglossal duct cysts: A validation study.

Objectives: To evaluate the use of ultrasound to distinguish between thyroglossal duct cysts (TGDC) and dermoid cysts (DC) for surgical planning. To validate the SIST (septae + irregular wall + solid components = TGDC) scoring system proposed by Oyewumi et al. [1].

Can lateral nasopharyngeal radiographs be used to predict eustachian tube dysfunction?

The objective of our case-control study was to determine whether craniofacial features on lateral nasopharyngeal radiographs (LNPRs) can predict eustachian tube dysfunction (ETD). The study included patients seen in the otolaryngology clinic from 2005 to 2011. Patients 0 to 10 years old with pressure equalization tube (PET) placement and LNPR within 6 months were included.

Acute abdominal pain in children: usefulness of three-view abdominal radiographs in the emergency department.

Diagnostic imaging is often an integral component in the workup of a pediatric patient with acute abdominal pain. The purpose of this study was to compare the diagnostic value of a three-view acute abdominal series (AAS) with that of a single supine view (SSV) in children with acute abdominal pain. All subjects aged ≤18 years that underwent an emergency three-view AAS examination for acute abdominal pain at a single urban hospital system were included.

Pentalogy of cantrell: surgical resection of a biventricular diverticulum.

Pentalogy of Cantrell is a rare diagnosis consisting of several midline defects of the sternum, abdominal wall, diaphragm, pericardium, and heart. One of the known features is ventricular diverticulum that can represent a technical challenge surgically. This is a follow-up case report of the successful simultaneous resection of a biventricular diverticulum and omphalocele repair after previous report of repair of complex intracardiac disease in the same patient.

Contrast-to-noise ratio and low-contrast object resolution on full- and low-dose MDCT: SAFIRE versus filtered back projection in a low-contrast object phantom and in the liver.

Objective: The purpose of this article is to evaluate the effect of sinogram-affirmed iterative reconstruction (SAFIRE) on contrast-to-noise ratio (CNR) compared with filtered back projection (FBP) and to determine whether SAFIRE improves low-contrast object detection or conspicuity in a low-contrast object phantom and in the liver on full- and low-dose examinations.

Subjects And Methods: A low-contrast object phantom was scanned at 100%, 70%, 50%, and 30% dose using a single-source made of a dual-source MDCT scanner, with the raw data reconstructed with SAFIRE and FBP. Unenhanced liver CT scans in 22 patients were performed using a dual-source MDCT.
