2. 6. Pre-Clinical Evaluation of a Novel Radiotracer for the Diagnosis of DVT and Pulmonary Embolism

   Author : David Edwards; Håkan Ahlström; Stuart McCully; Hans Johnsson; Uppsala universitet; []
   Keywords : Radiology; Radiologisk forskning;

   Abstract : Deep vein thrombosis (DVT) and pulmonary embolism (PE) are different aspects of a single condition, venous thrombo-embolic disease (VTE), a major cause of morbidity and mortality in the western world. Rapid diagnosis is critical, as timely medical intervention can have a substantial beneficial effect on the mortality rate. READ MORE

4. 7. On Renal Artery Stenosis

   Author : Hampus Eklöf; Rickard Nyman; David Bergqvist; Bertil Andrén; Lars Lönn; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Renal artery obstruction; Comparative studies; Contrast media; adverse events; Revascularization; Radiologisk forskning; Radiological research; Radiologisk forskning;

   Abstract : Renal artery stenosis (RAS) is a potentially curable cause of hypertension and azotemia. Besides intra-arterial renal angiography there are several non-invasive techniques utilized to diagnose patients with suspicion of renal artery stenosis. READ MORE

5. 8. Transcatheter Arterial Embolization in the Management of Life Threatening Bleeding Applied in Upper Gastrointestinal and Post Partum Bleedings

   Author : Lars-Gunnar Eriksson; Rickard Nyman; Sven Gustavsson; Krasnodar Ivancev; Uppsala universitet; []
   Keywords : Radiology; Post partum hemorrhage; Upper peptic ulcer bleeding; Transcatheter arterial embolization; Endoscopic treatment; Endoscopic marking; Metallic clip; Radiologisk forskning;

   Abstract : Transcatheter Arterial Embolization (TAE) is a method in which a catheter is inserted into an artery under fluoroscopy guidance. By using material that creates a thrombus, inserted through the catheter, the artery can be occluded and the bleeding stopped. READ MORE

6. 9. The Utility of Manganese for Magnetic Resonance Imaging of Transient Myocardial Ischemia

   Author : Rolf Eriksson; Håkan Ahlström; Tomas Bjerner; Håkan Arheden; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Radiologisk forskning; Radiological research; Radiologisk forskning; radiologi; Radiology;

   Abstract : In order to improve the diagnosis of coronary artery disease, better methods for detection of myocardial perfusion defects would be useful. One of the methods used for myocardial perfusion evaluation today is magnetic resonance imaging. READ MORE

   Abstract : Early detection is vital to successfully treating breast cancer, and mammography screening is the most efficient and wide-spread method to reach this goal. Imaging low-contrast targets, while minimizing the radiation exposure to a large population is, however, a major challenge. READ MORE
