2. 1. Image Quality Optimisation and Dose Management in CT, SPECT/CT, and PET/CT

   Author : Marcus Söderberg; Malmö Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CT; SPECT; PET; dosimetry; image quality; optimisation; dose reduction; automatic exposure control; contrast medium; phantom; image reconstruction; human observer;

   Abstract : The significant increase in the use of CT, alone or combined with SPECT or PET, has raised concerns about patient radiation exposure and the consequent increased risk of malignancy later in life. The overall objective of this work was to evaluate and optimise different approaches for minimising patient radiation absorbed dose and maintaining or improving image quality in CT, SPECT/CT, and PET/CT.

4. 2. Colorectal Liver Metastases. Aspects on Diagnosis and Surgical Treatment

   Author : Björn O B Ohlsson; Lund Kirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; carcinoembryonic antigen; fine-needle aspiration cytology; intraoperative ultrasonography; computed tomography; dearterialization; liver resection; Colorectal cancer; liver metastases; follow-up; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

   Abstract : Liver is the most common site of dissemination in colorectal cancer, and untreated liver metastases are associated with a poor prognosis. The main reason for trying to detect liver metastases early is that liver resection offers a chance for cure in selected patients. READ MORE

5. 3. Severe and moderate alpha-1-antitrypsin deficiency at the age of 30

   Author : Elisabeth Bernspång; allergologi och palliativ medicin Lungmedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cohort; screening; alpha-1-antitrypsin; lung function; CT densitometry; liver;

   Abstract : Alpha-1-antitrypsin (AAT) is a glycoprotein synthesised in the liver. Its main role is to protect lung tissue from destruction by neutrophil elastase. In severe (PiZZ) AAT deficiency, there is an increased risk of emphysema, especially in smokers. READ MORE

6. 4. Resection of colorectal liver metastases - Impact of preoperative chemotherapy

   Author : Sam Eriksson; Lund Kirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal liver metastases; Preoperative chemotherapy; Liver resection; Hepatic microcirculation; Sarcopenia;

   Abstract : Background Colorectal cancer is a leading cause of cancer related death worldwide. 20-30 % of patients will develop colorectal liver metastases (CRLMs). Surgical resection is the mainstay of treatment for CRLMs, and is often combined with perioperative chemotherapy, which can prolong progression-free survival after resection. READ MORE

7. 5. Monitoring of neuroendocrine tumor patients undergoing systemic therapies

   Author : Olof Pettersson; Anders Sundin; Håkan Geijer; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Therapy monitoring; NET; neuroendocrine tumor; computed tomography; CT; PRRT; 177Lu-DOTATATE; TGR; tumor growth rate; theranostics; DOTATOC-PET CT; Radiology; Radiologi; Endokrinologi och Diabetologi; Endocrinology and Diabetology; Oncology; Onkologi;

   Abstract : Monitoring of neuroendocrine tumor (NET) patients undergoing systemic therapies is troublesome as biomarkers capable of detecting tumor responses have been difficult to establish. Changes in the sum of target lesion diameters are used to evaluate the effects of therapy according to the response evaluation criteria in solid tumors (RECIST 1.1). READ MORE
