The CT scout view: does it need to be routinely reviewed as part of the CT interpretation?

Objective: The objective of our study was to determine whether the CT scout view should be routinely reviewed by comparing diagnostic information on the scout view with that provided by the correlative CT study.

Materials And Methods: Two radiologists blinded to history and CT findings reviewed retrospectively 2032 scout views. All cases with major findings (defined as any abnormality that would prompt additional diagnostic tests or require management) were correlated with the CT study, other imaging study, or medical record when necessary by a third radiologist to determine the validity of the scout view finding and whether the finding was identifiable on the current CT study.

The use of low-osmolar water-soluble contrast in videofluoroscopic swallowing exams.

The selection of the contrast agent used during fluoroscopic exams is an important clinical decision. The purpose of this article is to document the usage of a nonionic, water-soluble contrast (iohexol) and barium contrast in adult patients undergoing fluoroscopic exams of the pharynx and/or esophagus and provide clinical indications for the use of each. For 1 year, data were collected on the use of iohexol and barium during fluoroscopic exams.

A case-control comparison of lingual tonsillar size in children with and without Down syndrome.

Objectives/hypothesis: Lingual tonsillar hypertrophy is a common cause of persistent obstructive sleep apnea following adenotonsillectomy in the pediatric population and may be more prevalent in patients with Down syndrome (DS). We sought to quantify lingual tonsil size in pediatric DS patients and compare these findings to those of nonsyndromic children using cervical spine (c-spine) radiographs.

Study Design: Case control study.

Radiation safety for the speech-language pathologist.

It is the responsibility of the medical Speech-Language Pathologist (SLP) who performs video-assisted fluoroscopy of swallowing (VFSS) to be aware of guidelines, recommendations, and preventive measures to reduce radiation to oneself and the patient. Established parameters to reduce radiation during videofluoroscopy include keeping the exposure time brief, using lead aprons and other shielding, and maximizing the distance from the source of radiation. The purpose of this study was to measure radiation exposure to SLPs in the clinical setting and to provide practical recommendations to keep radiation exposure as low as reasonably achievable.

The use of iohexol as oral contrast for computed tomography of the abdomen and pelvis.

Positive oral contrast agents (high-osmolar iodinated solutions [high-osmolar contrast medium] or barium sulfate suspensions) are used routinely for abdominal computed tomography. However, these agents are not ideal. Patients complain about the taste and, sometimes, refuse to drink the required quantity.
