Looking Outside the Box of the Heart: Non-Cardiac Findings Encountered During Coronary CT Angiography
Author: Francesca Pugliese, MD, PhD and Simon PG Padley, FRCP FRCR
Although the purpose of most cardiac gated computed tomography (CT) studies is the assessment of cardiac structures, incidental findings are common. These may be detected within the small field of view images of the heart but increase in number when larger field .... Read more...
The role of multidetector CT in the
management of acute gastrointestinal bleeding
Author: Shuvro H. Roy-Choudhury and Anthony Nicholson
There is no universal consensus on the pathways used in
the diagnosis and management of acute gastrointestinal
(GI) bleeding. Endoscopy forms the mainstay of diagnosis
and management. This is supplemented by nuclear
medicine studies in diagnosis, and surgery together with
interventional embolisation, in management. Read more...
Multidetector CT in acute chest pain: the UK perspective
Author: Will Roberts, Ben Timmis, Adam Timmis
CT technology has for many years now been the principal means of investigation for patients presenting with suspected aortic pathology such as dissection or rupture and more recently has become established as the imaging modality of choice in patients with suspected pulmonary embolism. Read more...
The impact of new CT technology on clinical practice
Author: Christoph Becker, MD
With the introduction of multi-detector-row CT (MDCT), new applications such as cardiac CT angiography, lung and colon screening and scanning of polytrauma patients became feasible. Coronary artery disease can reliably be ruled out by MDCT and... Read more...
CT-colonography or colonoscopy -
Virtual colonoscopy
Author: Andrea Laghi
CT colonography, also known as virtual colonoscopy (VC), is a noninvasive test for the examination of the colon. The technique is easy, less labour-intensive than barium enema and conventional colonoscopy and is inherently safer since no adverse event or procedure-related complications have ever been reported. Read more...
Should integrated PET/CT be used for thoracic lesions?
Why is integrated PET/CT attractive?
Author: Egbert U. Nitzsche, Matthias Bruehlmeier, and Thomas Roeren
Imaging has emerged to have a central role in oncology based on its use in screening, diagnosis, staging, treatment planning, evaluation of response to treatment, and follow-up. Read more...
Population and patient risk from CT scans
Author: David Sutton
The recent rapid increase in the use of computed tomography (CT) scanning has been paralleled by increased concern about the doses of radiation involved and, in particular, about the public health consequences in terms of increased cancer induction. Read more...
Multidetector CT: can it provide a global evaluation of the patient presenting to the emergency department with chest pain?
Author: Charles S. White
In patients who present to the emergency department with acute chest pain, distinguishing between insignificant and life-threatening causes remains a major challenge. Initial evaluation with history, electrocardiography and biochemical markers is often unrevealing, leading to further work-up. Read more...
The role of CT in defining criteria for tumour response
Author: Angela M Riddell,
Dow-Mu Koh, Mike King
This article reviews the methods of assessing tumour response using CT, describing the more traditional methods (based on an alteration in tumour size) such as Response Evaluation Criteria in Solid Tumours (RECIST), and also the emerging techniques using functional imaging. Read more...
PET-CT: principles and practices
Author: Gustav K von Schulthess
Positron emission tomography-computed tomography (PET-CT) is the fastest-growing imaging modality worldwide. Integration of a PET scanner and CT scanner to provide co-registered images combines the high spatial resolution and anatomical detail of CT with the molecular... Read more...
CT-colonography or colonoscopy
- The case for colonoscopy
Author: Cesare Hassan and Angelo Zullo
Colorectal cancer (CRC) is the second-leading cause for cancer-related death worldwide. Colonoscopy is a safe procedure which can identify colorectal polyps and early cancers with the highest accuracy, and
efficaciously remove them. Read more...
Should integrated PET/CT be used for thoracic lesions?
A critical appraisal
Author: Albrecht Kretzschmar and Peter C. Thuss-Patience
Integrated positron emission tomography-computed tomography (PET/CT) is an innovative imaging test offering the potential for a higher degree of accuracy and sensitivity compared with plain radiographic investigations. Read more...
