Dose Exposure Levels in 16-Row MSCT and 64-Row MSCT

We evaluate the impact of scan length on the exposure levels at 16-row multislice computed tomography (MSCT) and 64-row MSCT. Dose length product (DLP) values were determined to compare exposure levels in 16- and 64-row MSCT. For scan slice thickness under 2 mm, the exposure levels of 64-row MSCT are lower than those of 16-row MSCT when scanning an object larger than 12.3 cm. At this value the plots of the 16- and 64-row DLP values versus scan length cross. The crossing of DLP curves obtained in MSCT at different numbers of detector rows has not been published before. Differences in object size may thus explain apparent discrepancies between previous studies reporting either higher or lower effective exposure levels at 64-row MSCT as compared with 16-row MSCT.Read...

In computed tomography (CT) the number of detector rows has doubled annually over the last eight years. New image reconstruction algorithms have adapted to the requisite extended cone angles. An advanced 3D reconstruction algorithm called coneXactTM was developed for Aquilion ONETM (Toshiba Medical Systems Corporation, Tokyo, Japan). This algorithm doubles the number of slice images combined with artefact suppression.Read...

Advancing Pediatric Imaging with 16-Slice CT

Posted: 4.03.2010

Pediatric imaging presents many unique and difficult challenges to the radiologist. Correct and rapid diagnosis is extremely important in pediatric imaging and to that end we constantly strive for tests that offer more information, accuracy and versatility. However, it is also our duty to provide tests that are safe and minimise exposure to ionizing radiation.Read...

64-Slice Scanning

The fastest, most powerful computed tomography (CT) scanner on the market is now available at St. Mary’s Hospital. St. Mary’s state-of-the-art Toshiba Aquilion 64 CFX scanner is so fast it can synchronize with the patient’s heart rhythm and capture images between beats. St. Mary’s is the first health care provider in Northeast Georgia to offer this powerful new diagnostic tool to the community. In a matter of seconds, the Aquilion 64 can create photo-quality images of the inside of the body -- painlessly. Three-dimensional images of the heart, brain, circulatory system, skeletal system and internal organs can be obtained in about 15 seconds, allowing physicians to diagnose narrowed arteries, internal bleeding, early stage cancers and much more.Read...
