Fracture Detection: A Possible Method to Aid in Diagnosis and Improve Reporting Accuracy.
Joseph Gagliardi, M.D. touches upon various quality of care issues in his article on Fracture Detection. From diagnostic accuracy in the Emergency Room, to the value of patient reporting, to the usefullness of standard hospital routines, Dr. Gagliardi's discussions should get you thinking about the complexities of correct radiological diagnosis and the radiologist's responsibility for accuracy.

Evaluation of the Coronary Artery by Helical CT Using Retrospective ECG-Gating

Dr. Hiramatsu and colleagues utilized retrospective ECG-gating to capture static views of the coronary artery. This study of 31 patients in Japan demonstrated good correlation between calcification score and degree of stenosis and is a promising application for helical CT in cardiac imaging.

Musculoskeletal Cartilage Lesions Encountered in Clinical Practice: Part Two
In Part Two of Cartilage Lesions, Dr. Gagliardi discusses chondrosarcoma as the primary malignancy diagnosed in his clinical practice. Of particular interest are Dr. Gagliardi's insights into imaging strategies for maximizing surgical management of suspected chondrosarcoma, and considerations for distinguishing chondrosarcoma vs. enchondroma.

Musculoskeletal Cartilage Lesions Encountered in Clinical Practice: Part One
Dr. Joseph Gagliardi summarizes the imaging features and anatomical characteristics for five types of benign cartilage lesions. His comprehensive descriptions cover enchondromas, osteochondromas, chondroblastomas, periosteal chondromas, and chondromyxoid fibromas.

Evaluation of CT Perfusion Imaging in the Intravenous Thrombolysis Treatment of Acute Ischemic Stroke Within Twelve Hours

Dr. Dai, along with colleagues Drs. Liu and Guan, studied the usefulness of CT perfusion imaging of ischemic changes in patients evaluated within twelve hours of stroke onset.

Primary Malignant Hepatic Neoplasms of Adults
Hepatocellular carcinoma, fibrolamellar carcinoma, and cholangiocarcinoma are featured in Dr. Peter Buetow's "visual essay" on primary hepatic neoplasms in adults.

Ring Enhancing Lesions

Dr. Kohli analyzes a previous RadiologyWeb article written by Dr. J. Smirniotopoulos and presents a new differential diagnosis list based on his clinical experience in the Indian subcontinent.

Functional Evaluation of Joints using Kinematic MRI: Part I.
Kinematic MRI technology allows visualization of the soft tissues and bony anatomical features within specific joints over a range of motion. Advantages of this functional imaging and clinical applications for the technique are described for the ankle, cervical spine, and knee in this segment.

Functional Evaluation of the Joints using Kinematic MRI: Part II. Shoulder and Wrist
Part Two of Kinematic MRI explores the clinical advantages to imaging the wrist and shoulder through a range of motion. Kinematic MRI helps reveal instability and impingement within the glenohumeral joint and may be useful in assessing ligament defects, intercarpal spacing, and carpal instability in the wrist.
