2. 6. Artificial Intelligence-based Assessment of Prostate Cancer Metastases in PET/CT

   Author : Sarah Lindgren Belal; Malmö Nuklearmedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Artificial intelligence AI ; Convolutional neural networks CNN ; PET CT; Prostate cancer; Automated; Tumor burden; Bone metastases; Lymph node metastases;

   Abstract : Background: Quantification of tumor burden from bone scan in the form of automated Bone Scan Index (aBSI) has been validated as an imaging biomarker for patients with prostate cancer. Positron emission tomography combined with computed tomography (PET/CT) is more sensitive and accurate compared to conventional imaging such as bone scan. READ MORE

4. 7. Detecting prostate cancer metastases - PET/CT and the sentinel node technique

   Author : Henrik Kjölhede; Malmö Urologisk cancerforskning; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; Metastases; PET CT; Choline; Fluoride; Sentinel lymph nodes;

   Abstract : Prostate cancer is one of the most common malignancies. Its treatment is highly dependent on the presence or absence of metastases. The available invasive and non-invasive modalities for detecting metastases are imperfect. READ MORE

5. 8. Investigation of Bladder Tumors with CT Urography in Patients Presenting with Gross Hematuria

   Author : Malin Helenius; Anders Magnusson; Torbjörn Andersson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CT Urography; Bladder tumor; Gross hematuria; Tissue charactarization; Bladder distension; Tumor detection; Radiology; Radiologi;

   Abstract : Bladder tumor is the most common tumor detected in patients presenting with gross hematuria. Early detection and treatment is crucial for good prognosis, however, delay in diagnosis and treatment is common. Routine work-up of gross hematuria includes cystoscopy and Computed Tomography Urography (CTU). READ MORE

6. 9. Rectal cancer surgery : Defunctioning stoma, anastomotic leakage and postoperative monitoring

   Author : Peter Matthiessen; Olof Hallböök; Rune Sjödahl; Lars Påhlman; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anterior resection of the rectum; total mesorectal excision; TME; anastomotic leakage; defunctioning stoma; risk factors; intraoperative adverse events; population based study; postoperative monitoring; CT-scan microdialysis; cytokines; Surgery; Kirurgi;

   Abstract : The understanding of the mesorectal spread in rectal cancer has lead to wide acceptance of total mesorectal excision (TME) as the surgical technique of choice for carcinoma in the lower and mid rectum. While oncological results and survival have improved with TME-surgery, morbidity and mortality remain important issues. READ MORE

7. 10. Measurement accuracy. Applications in X-ray computed tomography (CT) dose reduction and magnetic resonance spectroscopy (MRS) volume selection

   Author : Göran Starck; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CT; Radiation exposure; Image quality; Tissue characterisation; MRS volume selection; Signal profile; Phantom; Magnetic susceptibility;

   Abstract : X-ray computed tomography (CT) images of transaxial cross sections of the body can be used to determine tissue volumes. However, the considerable radiation dose associated with high-quality clinical images has greatly limited the use of CT for this application. READ MORE
