CIN and clinical research: How should we interpret the data?
Abstract
When interpreting clinical papers, it is important that a number of key principles are considered. These include internal validity (the robustness of the conclusions drawn from the study), external validity (the relevance of the study's results to the broader population), power, and clinical relevance.

Population and patient risk from CT scans
Abstract
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. Despite the fact
that CT only accounts for ~10-15% of all radiological
procedures, it contributes around 50% of the collective
dose to the population arising from diagnostic
radiology. Because of the relatively high organ doses
associated with CT, it is possible to produce ....

Gadolinium and NSF
What is fact and what is theory?
Abstract
Since the publication by Grobner and colleagues in
2006 that first suggested the association between
gadolinium-based contrast agents (GBCA) and
nephrogenic systemic fibrosis (NSF), there have been
many articles published on the subject.

Percutaneous device closure for patent foramen ovale
Author: Sam Firoozi and Stephen J Brecker
The patent foramen ovale (PFO) is a very common anatomical variant of the interatrial septum and is associated with a number of paradoxical embolism syndromes including cryptogenic stroke, decompression illness in divers and migraine with visual aura. 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...
Stress Cardiovascular MR Imaging
Author: Oliver Strohm and
Matthias G. Friedrich
Stress testing in patients with ischaemic heart disease is
commonly applied in clinical practice. Cardiovascular MRI
has the ability to obtain precise information about left
ventricular function ... Read more...
The use of drug eluting stents for coronary artery disease
Author: Peter Barlis, MBBS, MPH,
FRACP
Jun Tanigawa, MD,
Carlo Di Mario, MD, PhD
The growth in the availability and use of drug eluting
stents has seen the interventional cardiologist tackle
more lesions with increasing complexity and in higherrisk
patients. Read more...
Percutaneous nephrostomy and antegrade ureteric stenting
Author: Tze Wah
The past 30 years have seen a remarkable increase in interventional uroradiological procedures. There is now a wide variety of procedures for patients who require long-term urinary drainage with percutaneous nephrostomy (PCN) or ureteric stenting. Read more...
Use of cerebral protection during carotid artery stenting
Author: Bernhard Reimers
Carotid artery stenting (CAS) is emerging as a less invasive alternative to carotid endarterectomy, although embolic neurological events occur invariably during CAS. Read more...
New stent technologies: coated, covered and bifurcated stents
Author: Chidambaram Rammohan,
Ata Erdogan and
Charles J. Davidson
Specific anatomic challenges and in-stent restenosis have been the impetus for new designs in stent technology. Drug-eluting stents, particularly the sirolimus-coated and paclitaxel-coated stents have shown efficacy in clinical trials. Read more...
Subintimal angioplasty
Author: Michael J. Glasby, George Markose and Amman Bolia
The technique of subintimal angioplasty (SIA) has
been in use for approximately two decades and is a
suitable alternative to bypass surgery. Read more...
Management of left main coronary artery disease: CABG is still the best therapy
Author: David P. Taggart
This article reviews the pathophysiology of left
main stem stenosis and the rationale for coronary
artery bypass graft (CABG) surgery and stenting. Read more...
Left main stem stenting
Author: Anthony H Gershlick
Percutaneous treatment of obstructive coronary disease has, for a number of years, been undertaken more commonly than the coronary artery bypass graft (CABG). Technical developments, operator skill and the advent of drug-eluting stents has meant that most lesions can be treated effectively with little associated morbidity and with rapid patient discharge. Read more...
Carotid artery stenting without cerebral protection
Author: Arnd Doerfler, Tobias Engelhorn and Michael Forsting
Carotid angioplasty and stenting is increasingly used as an attractive alternative to carotid endarterectomy (CEA) for treatment of symptomatic and asymptomatic carotid artery disease. Read more...
The balance of evidence for carotid artery stenting with cerebral protection
Author: Antonio Colombo and
Ioannis Iakovou
Although endarterectomy is today considered the gold-standard therapy for the treatment of carotid artery stenosis, the approach is not free of complications. Carotid artery stenting (CAS) has rapidly emerged as an equivalent alternative to Read more...
Patient selection and imaging assessment for abdominal aortic aneurysm stent grafting
Author: Michel Nonent, Ali Badra and Pierre Gouny
Endovascular repair using stent-grafts for abdominal aortic aneurysms (AAAs) is becoming increasingly employed worldwide. Imaging has great importance in the assessment of AAAs and in decision-making. Read more...
