Musculoskeletal MDCT

MDCT of Abdominal Trauma

Trauma is a significant public health problem, representing the third leading cause of death in the United States. Trauma is also the leading cause of mortality in Americans under the age of 40. With the widespread availability of multidetector-row computed tomography (MDCT) in trauma centers, the traditional workup of trauma patients has changed. Blunt chest injuries are now frequently studied...

MDCT of abdominopelvic oncologic emergencies

Acute complications arising in abdominopelvic malignancies represent a unique subset of patients presenting to the emergency room. The acute presentation can be due to complications occurring in the tumor itself or visceral or vascular structures harboring the tumor. Multidetector computed tomography (MDCT) is the investigation of choice in the workup of these patients and enables appropriate a...

MDCT of small bowel tumours

Primary benign and malignant neoplasm of the small bowel are rare. Malignant tumours often present late symptoms resulting in a poor prognosis. Early detection of small bowel neoplasms is desirable but challenging for both clinicians and radiologists. Conventional double contrast enteroclysis was the method of choice in small bowel imaging but is increasingly being replaced by cross-sectional i...

A Low - Delay MDCT / IMDCT

© 2013 Sangkil Lee and Insung Lee 935 This letter presents an algorithm for selecting a low delay for the modified discrete cosine transform (MDCT) and inverse MDCT (IMDCT). The implementation of conventional MDCT and IMDCT requires a 50% overlap-add (OLA) for a perfect reconstruction. In the OLA process, an algorithmic delay in the frame length is employed. A reduced overlap window and MDCT/IM...
