Head and Neck Imaging

Multislice computed tomography (MS CT), which was introduced to clinical imaging as fourslice detectors in 1998 has fully proven its superior performance over conventional scanner technology. For example, it provides optimized resolution of detail and increased scan speed. Simultaneously, this technology has opened new indications for computed tomography, for example, in heart imaging. However,…

Methods and Results of Radiation Exposure Reduction Using Multislice CT

The number of CT examinations undertaken over the past few years has increased remarkably worldwide due to the new diagnostic possibilities afforded by multislice computer tomography (MSCT). As the new technology is gaining ground, many researchers and radiologists are looking for ways to reduce patient radiation exposure. In 2001, Giacomuzzi et al.1 of Innsbruck reported an up to 2.6-fold…

A Small Primer on the Clinical Use of MSCT for Heart Exams

Because of the rapid technical and scientific development over the past few years, multislice computer tomography of the heart has become increasingly established in the clinical routine. This requires, among other things, knowledge of the anatomy of the coronary arteries, the meaningful evaluation of the calcium score and the appropriate reproduction of the function of the left ventricle.

Optimization of Temporal and Spatial Resolution for Cardiac CT Diagnostics

Further developments in computer and detection technology over the last few months and years have made it possible to overcome, to a large degree, the previously limitations of medical computer tomography in spatial and temporal resolution, and thus to permit “detail-true” representation of the beating heart. The diagnostic workflow and computer-tomographic diagnosis of the heart using the…

Optimization and Reduction of CT Radiation Exposure

The exposure of patients to radiation by computed tomography has been widely discussed in recent years, both by professionals and by the public. The essential reason for optimizing patient exposure is the basic desire to keep radiation dose at the lowest possible level. This requires above all organ-specific and patient-specific adjustment of the radiation exposure in order to achieve uniform…

Virtual Coloscopy

Increasingly more importance is being ascribed to early detection of colon carcinoma and of its precursor stages, since there has been a practically twofold increase in the incidence of this disease in Germany over the past 20 years. With a combination of 1. case history, 2. rectal palpation result, 3.'blood in stools' test (haemoccult) and 4. coloscopy, many conspicuous changes to the intestinal…

Tumour Characterization Using Micro Flow Imaging

Due to echogenicity differences in comparison with the surrounding liver tissue conventional B-mode-imaging sonography permits the unambiguous classification of the frequently occurring typical liver cysts (criteria: round, echo-free, smoothly demarcated, with edge shadows and sound through transmission) and calcifications (highly reflective, acoustic shadows). The detection and characterization…

CT in Oncology

Modern oncology with its improved options holds out prospects for many novel curative and palliative procedures. By adopting a multidisciplinary approach to diagnosis, treatment and follow-up care these prospects can become reality, with radiology playing a pivotal role. This role encompasses imaging diagnostics for all tumour entities as well as diagnostic and therapeutic interventions.…

Cardiac Multislice Computed Tomography (MSCT) Angiography

Spiral computed tomography first allowed the seamless acquisition of entire volumina without first separating them into individual slices. With the newest generation of MSCT devices having the 16-slice technology, short gantry rotation time of < 0.5 seconds, and a high performance processor, it is now possible to acquire large amounts of data in a short period of time with high spatial and…

Diagnosis of Cardiac Diseases

For decades, non-invasive cardiac assessment has been at the center of interest. Non-invasive imaging modalities, such as MSCT, MRI, SPECT, PET, and echocardiography, provide valuable cardiac information, and all have been used to measure cardiac morphology, function, perfusion, viability of myocardium, and coronary anatomy for clinical management and research. The last decade brought major…

Stroke Imaging: The Procedure in Practice

In the past, native computed tomography of the neurocranium (CCT) was often the only procedure to diagnose a stroke. Technical limitations of previous generations of scanners made their use impractical for complementary methods of visualising blood vessels or for perfusion imaging. With the introduction of multi-slice spiral CT these technical limitations disappeared and both perfusion CT (PCT)…

Stroke Imaging: Foundations and Strategy

Diagnostic imaging is of particular value in investigating ischaemic cerebrovascular accidents since, due to the rapid progression of cell destruction in the region of the cerebral infarction, the radiologist is faced with urgent questions regarding a possible procedure. These questions may be answered particularly well using computed tomography (CT). The following article provides an overview…

3D USCT nears reality

Back in the 70s, when scientists first speculated on the development of 3-D ultrasound computed tomography (3-D USCT) the available technology could not equal their dreams. Now, before the end of 2007, a prototype at Germany's Karlsruhe Research Centre will be used for the first in-vivo tests.

The RSNA 2005

Late in November and into early December, as icy air streamed over the shores of Lake Michigan - affirming the nickname `windy city´ for Chicago - radiologists continued to immigrate here en masse for their biggest annual gathering. This year the Radiological Society of North America (RSNA) held its 91st annual meeting, parallel with the scientific congress and trade fair. The exhibition alone…
