Preliminary Clinical Results with Precision Imaging Technology
Ultrasonography offers a wide range of highly sophisticated technological options, chief among them being sensitive vascularization methods such as power Doppler or ADF, contrast media, 3D techniques and elastography. However, B-mode imaging remains the indispensible mainstay of ultrasound diagnostics and imaging. In most cases, tissue structures can only be visulized and differentiated in B-mode.Read...
What is Special about Tomotherapy? Quite simply, tomotherapy represents the future of radiation therapy. The leap in technology from regular radiation therapy is overwhelming. Hi-Art Tomotherapy™ shares a lot of technology with CT scanners, otherwise known as computerized tomography. The machine even looks like a CT scanner.Read...
Best MRImage 2008
As every radiologist has his or her specific area of interest, each individual creates protocols that are optimized to match these interests. In order to share this experience with colleagues, Toshiba wanted to invite customers to contribute their selected cases, enabling us to distribute these ideas on optimal imaging techniques with other and future Toshiba Vantage MR users. In April 2008, Toshiba Medical Systems Europe therefore asked all customers in Europe to share their high-quality MR images or interesting clinical cases for The MR Image of the Year 2008.Read...
Top-Performing Medical Equipment Companies Announced
OREM, Utah – Jun 15, 2009 – Healthcare research firm KLAS today released its annual rankings of the best-performing medical equipment vendors. Top-ranked companies in seven key market categories – including computed tomography (CT), digital mammography, smart pumps and ultrasound – have earned the 2009 Best in KLAS distinction, signifying their leadership in meeting customer expectations. Based on evaluations submitted by thousands of healthcare providers throughout the United States and Canada, KLAS rankings measure a vendor’s performance in areas like product quality, implementation, and service and support. A Best in KLAS award is reserved for the top-rated companies in a select group of the largest and most impactful market segments.Read...
Clinical Applications of Advanced High Frequency Ultrasound Techniques
High frequency ultrasound techniques continue to improve with better resolution and exquisite Bmode imaging, particularly with improved compounding techniques as seen with the ApliPure+ product. Particular focus however has been paid to improving techniques for breast imaging and one novel idea is to be able to highlight microcalcifications within tissues.Read...
Microcalcification Detection in Breast Ultrasound – A New Perspective?
The prime task of diagnostic breast ultrasound is the focused rapid assessment of new findings on palpation, particularly in young women with dense mammary tissue. Optimization of the devices for this modality has resulted in high-resolution breast ultrasound which over the last few years has led to marked improvements in image quality, detail recognition and spatial resolution of the sonographic image. Techniques such as Tissue Harmonic Imaging (THI) and Spatial/Frequency Compounding (FC) have made it possible to visualize even the smallest changes in tissue. Read...
Elastography – A Safe Modality to Differentiate Breast Lesions with Ultrasound?
One important characteristic of tissue is its inherent elasticity which may be altered by pathophysiologic processes such as ageing, inflammation and malignant tumors. In this context elasticity is defined as the ratio of the tension (stress) needed to produce a relative change in length (strain) and describes how much pressure must be exerted on the tissue in order for it to undergo elastic deformation. In principle tissue elasticity can be derived from the stress and strain measured in the tissue structures. While strain can be computed easily based on the high frequency echo signals, stress cannot be determined directly from tissue measurements. Thus, compression must take place under standardized conditions.Read...
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...
Aquilion ONE 640 Multislice Reconstruction with Dynamic Volume CT
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
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...
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...
Calorie Restriction: Scientists Take Important Step Toward 'Fountain of Youth'
Going back for a second dessert after your holiday meal might not be the best strategy for living a long, cancer-free life say researchers from the University of Alabama at Birmingham. That's because they've shown exactly how restricted calorie diets -- specifically in the form of restricted glucose -- help human cells live longer.Read...
Cancers Can Vanish Without Treatment, but How?
Call it the arrow of cancer. Like the arrow of time, it was supposed to point in one direction. Cancers grew and worsened. But as a paper in The Journal of the American Medical Association noted last week, data from more than two decades of screening for breast and prostate cancer call that view into question. Besides finding tumors that would be lethal if left untreated, screening appears to be finding many small tumors that would not be a problem if they were left alone, undiscovered by screening. They were destined to stop growing on their own or shrink, or even, at least in the case of some breast cancers, disappear.Read...
