Electronic evaluation systems for radiology residency and fellowship.

Electronic evaluation systems are becoming more commonplace in radiology residencies. This article describes the authors' experience in the development of such a system and a method that a residency program or graduate medical education office could use to evaluate commercially available programs.

Review of technology: planning for the development of telesonography.

Teleradiology allows contemporaneous interpretation of imaging exams performed at some distance from the interpreting radiologist. The transmitted images are usually static. However, there is benefit to real-time review of full-motion ultrasound (US) exams as they are performed.

Bladder wall necrosis in an extremely low-birth-weight infant: a thought-provoking complication of necrotizing enterocolitis.

An 879-g baby boy had catastrophic necrotizing enterocolitis (NEC) at 29 days of life and underwent surgical laparotomy with a subsequent ileostomy and peritoneal drain placement. The infant was subsequently stable until 42 days of life when a spontaneous perforation of the bladder apex was diagnosed by a suprapubic cystogram. Laparotomy on day of life 46 found a loop of dead bowel herniating into a necrotic hole of the bladder dome.

Imaging the lungs in asthmatic patients by using hyperpolarized helium-3 magnetic resonance: assessment of response to methacholine and exercise challenge.

Background: Imaging of gas distribution in the lungs of patients with asthma has been restricted because of the lack of a suitable gaseous contrast agent. Hyperpolarized helium-3 (HHe3) provides a new technique for magnetic resonance imaging of lung diseases.

Objective: We sought to investigate the use of HHe3 gas to image the lungs of patients with moderate or severe asthma and to assess changes in gas distribution after methacholine and exercise challenge.

Conversion of teaching file cases from film to digital format: a comparison between use of a diagnostic-quality digitizer and use of a flatbed scanner with transparency adapter.

Rationale And Objectives: The authors' institution had decided to convert its radiology teaching files from film to digital media. This study was performed to determine the simplest method for converting the analog film images to digital images without a subsequent loss in diagnostic accuracy.

Materials And Methods: Twenty chest radiographs that demonstrated interstitial lung disease were randomly selected from the departmental teaching files and matched with 20 control radiographs from healthy adults.
