Objectives To compare the effective radiation dose (ERD) needed to obtain information on coronary anatomy and physiology by a non-invasive versus an invasive diagnostic strategy.Background Knowledge of anatomy and physiology is needed for management of patients with coronary artery disease (CAD). There is, however, a growing concern about detriment...

To determine retrospectively the additional value of DWI-MRI toT2-MRI for predicting complete response (ypT0N0 = CR) after chemoradiation-therapy (CRT) in locally advanced rectal cancer. Seventy locally advanced rectal cancer patients underwent CRT followed by restaging MRI and resection. Two readers with different experience levels independently s...

The purpose of our study is to model cost-effectiveness of MDCTA for the diagnosis of NSTE-ACS with initially negative enzymes, in the emergency department. In Belgium, the use of multi-detector computed tomography (MDCTA) is probably cost-effective in the diagnosis of NSTE-ACS in the acute setting A decision tree model was developed and a mathemat...

We describe a patient who presented with a giant ovarian cyst causing a complete occlusion of the distal abdominal aorta. An 86-year-old patient presented with acute ischaemia of her lower limbs 3 days after a transurethral resection of a bladder tumour (TURT). She refused treatment for her giant ovarian cyst. The administration of Sintrommitis® wa...

Sudden thrombosis of an abdominal aortic aneurysm is a rare condition with a high mortality rate. We present a patient with acute neurological deficits in both legs based on a thrombosis of a nine centimetre infrarenal abdominal aortic aneurysm. Successful iliac thrombectomy with aortic tube graft reconstruction was performed. Sudden thrombosis of...
