Quantitative first pass perfusion in cardiovascular magnetic resonance for determination of peak ventricular transit time--a technique for evaluation of heart function.

Background: The aim of this study was to determine peak ventricular transit time (PVTT) using cardiac magnetic resonance (cMRI) imaging with first-pass perfusion and to evaluate PVTT as a potential new predictor of cardiac failure.

Methods And Results: cMRI was performed on 150 patients. The PVTT between the right and left ventricle was measured.

Cardiac magnetic resonance imaging as a tool to link cardiac conduction disease to myocarditis with minimal left ventricular impairment.

Myocarditis is an injury of the myocardium caused by a variety of agents. Conduction disturbances such as complete atrioventricular block (AV block) may occur as an infrequent but serious complication of myocarditis. Early detection and accurate diagnosis of myocarditis are still unresolved challenges.

Transthoracic sonography in comparison to multislice computed tomography in detection of peripheral pulmonary embolism.

The aim of the study was to compare transthoracic sonography (TS) with multislice computed tomography (MSCT) in the detection of peripheral pulmonary embolism (PE). In addition, the study verified peripheral parenchymal findings visualized by TS and MSCT. A total of 33 patients (16 females, 17 males; mean age = 65.

Computer-aided joint space analysis of the metacarpal-phalangeal and proximal-interphalangeal finger joint: normative age-related and gender-specific data.

Purpose: The purpose of the study was to provide reference data for computer-aided joint space analysis based on a semi-automated and computer-aided diagnostic system for the measurement of metacarpal-phalangeal and proximal-interphalangeal finger joint widths; additionally, the determination of sex differences and the investigation of changes in joint width with age were evaluated.

Patients And Methods: Eighty hundred and sixty-nine patients (351 female and 518 male) received radiographs of the hand for trauma and were screened for a host of conditions known to affect the joint spaces. All participants underwent measurements of joint space distances at the metacarpal-phalangeal articulation (JSD-MCP) from the thumb to the small finger and at the proximal-interphalangeal articulation (JSD-PIP) from the index finger to the small finger using computer-aided diagnosis technology with semi-automated edge detection.

Computer-aided joint space analysis (CAJSA) of the proximal-interphalangeal joint-normative age-related and gender specific data.

Rationale And Objectives: To provide reference data for computer-aided joint space analysis (CAJSA) based on a semiautomated and computer-aided diagnostic system for the measurement of joint space widths (ie, proximal-interphalangeal joint), considering gender-specific and age-related differences.

Materials And Methods: A total of 869 subjects were enrolled (351 females/518 males) with radiographs of the hand. All participants underwent measurements of joint space distances at the proximal-interphalangeal articulation (JSD-PIP) of the second to fifth finger using CAJSA technology.

Normative reference values of joint space width estimated by computer-aided joint space analysis (CAJSA): the distal interphalangeal joint.

Purpose: The study introduces reference data for a computer-aided analysis. The semiautomated computer-aided diagnostic system provides the estimation of joint space width at the distal interphalangeal joints, considering gender-specific and age-related changes.

Patients And Methods: 869 subjects (351 female/518 male) with hand x-rays were included and underwent measurements of joint space distances at the distal interphalangeal articulation (JSD-DIP) of the second to the fifth finger using computer-aided joint space analysis (CAJSA).

Normative data for digital X-ray radiogrammetry from a female and male German cohort.

This study presents German reference data for digital X-ray radiogrammetry (DXR) differentiated by males as well as females, and quantifies for gender-specific and age-related differences including all DXR parameters. This study also documents the effects of different X-ray settings (e.g.

Ancillary lung parenchymal findings at spiral CT scanning in pulmonary embolism. Relationship to chest sonography.

Introduction/objective: The aim of the study was to compare findings of transthoracic sonography (TS) and of spiral computed tomography (sCT) in patients with suspected pulmonary embolism (PE).

Methods And Patients: Peripheral parenchymal and pleural findings of TS and sCT were compared in 62 patients (25 females, 37 males; mean age 62.2 years) with suspected PE.
