RESUMEN
Aims To assess if there was a significant difference in the number of positive studies for pulmonary embolism between obese and non obese patients. Methods A retrospective analysis of all CTPAs performed in our institution over one year in patients aged 18-50 was performed. Data regarding the diagnosis of pulmonary embolism, the presence of airways disease, other significant chest findings, D dimer values and demographic data including a BMI surrogate was obtained. Results Two hundred and thirty CTPAs were performed in our institution over 12 months. Two hundred and twenty-one were included for analysis, of which 129 were male and 92 were female. Sixty-nine (31%) patients were classified as obese. Eleven (16%) of these had positive studies. One hundred and fifty-two patients were in the non obese category, of which 24 (15%) had positive studies. Conclusions We are not over imaging the obese patient, but are over imaging patients in general with suspected PE, but are exposing a significant number overall, to unnecessary radiation.

Carcinoid tumours in the abdomen are uncommon, but typically occur in the gastrointestinal tract. Primary renal carcinoid is an extremely rare tumour, poorly described in the literature. We describe an unusual case where an atypical renal mass on imaging led to a preoperative diagnosis of renal carcinoid on imaging guiding biopsy.

The aim of the study was to determine the added value of stroke protocol MRI following negative initial CT brain in the acute stroke setting. A retrospective study was performed over a 6 month period in a tertiary referral stroke centre. Patients were selected from the stroke and radiology databases. Inclusion criteria: clinical stroke syndrome, negative initial CT with subsequent MRI study with diffusion weighted sequences. Ninety two patients were reviewed and 73 (M:F of 39:34, mean age 62.1 ± 14.0 years) met the inclusion criteria. Twenty MRI studies (27.4%) were positive for acute/subacute ischaemia in the setting of a normal initial CT. The average time interval between initial CT and MRI brain imaging was 4.7 ± 2.6 days. Whilst CT continues to be the first line imaging investigation for acute stroke, MRI has substantial added value following negative initial CT in the diagnosis of stroke.
