CAD-based analysis improved the specificity compared with manual analysis of enhancement. Automated analysis at 50% and 100% thresholds showed a high sensitivity and specificity for readers with varying levels of experience.

This study highlights the need to inform radiologists of the relative risk when performing pre-surgical localisation after RSNI. This risk should be justified locally in accordance with the total dose received by the localising radiologist. Particular consideration should be given to pregnant staff and the possibility of performing wire localisations before radio-isotope injection.

Accuracy of dual-source computed tomography in quantitative assessment of low density coronary stenosis—a motion phantom study

DSCT enables highly reproducible quantification of low density stenosis, but underestimates the degree of stenosis, especially in small vessels. Area-based measurements reflect the true degree of stenosis with higher accuracy than diameter.

Immediate and long-term outcomes of bronchial and non-bronchial systemic artery embolisation for the management of haemoptysis

Chun, Joo-Young; Belli, Anna-Maria

2009 European Radiology

doi: 10.1007/s00330-009-1591-3pmid: 19727742

Bronchial artery embolisation (BAE) is an effective and safe procedure for haemoptysis control in most cases. However, high recurrence and mortality rates are associated with aspergilloma. Early intervention with repeat embolisation is recommended in these patients and elective surgery should be considered.

Analysis of the accuracy of high-resolution computed tomography techniques for the measurement of stapes prostheses

Bozzato, Alessandro; Struffert, Tobias; Hertel, Victoria; Iro, Heinrich; Hornung, Joachim

doi: 10.1007/s00330-009-1582-4pmid: 19727746

CT measurement consistently overestimated intravestibular piston dimensions and vestibular intrusion. Modern temporal bone imaging systems are not yet able to depict the stapes piston position with a sufficient degree of accuracy.

64-Slice CT angiography of the abdominal aorta and abdominal arteries: comparison of the diagnostic efficacy of iobitridol 350mgI/ml versus iomeprol 400mgI/ml in a prospective, randomised, double-blind multi-centre trial

Retrospective analysis of patients for development of nephrogenic systemic fibrosis following conventional angiography using gadolinium-based contrast agents

Hoppe, Hanno; Spagnuolo, Sara; Froehlich, Johannes; Nievergelt, Helga; Dinkel, Hans-Peter; Gretener, Silvia; Thoeny, Harriet

2009 European Radiology

doi: 10.1007/s00330-009-1586-0pmid: 19760239

Conventional arterial angiography with GDBCA may play a role in the development of NSF in patients with renal insufficiency. Alternative contrast agents, such as CO 2 angiography or rather the use of low doses of iodinated contrast agents, should be considered in these patients.

High resolution MMRSPI at 3 T using 1 M contrast agent under daily routine conditions provides reliable detection of stress-induced myocardial hypoperfusion with higher diagnostic accuracy than 1.5-T conditions.

When CAD output is ordered by CAD score, an initial period of rapid performance improvement slows significantly over time because of non-uniformity in the distribution of TP CAD output and not to a changing reader performance over time.

This study demonstrated the non-inferiority of the 350 versus 400 mgI/ml iodine concentration, in terms of diagnostic efficacy, in abdominal MDCT angiography. It also confirmed the high robustness and reliability of this technique across multi-national practices.
