Age prediction in sub-adults based on MRI segmentation of 3rd molar tissue volumes
Bjørk, Mai Britt; Kvaal, Sigrid Ingeborg; Bleka, Øyvind; Sakinis, Tomas; Tuvnes, Frode Alexander; Haugland, Mari-Ann; Lauritzen, Peter Mæhre; Eggesbø, Heidi Beate (Peer reviewed; Journal article, 2023)Purpose Our aim was to investigate tissue volumes measured by MRI segmentation of the entire 3rd molar for prediction of a sub-adult being older than 18 years. Material and method We used a 1.5-T MR scanner with a ... -
The choice of diagnostic modality influences the proportion of low muscle strength, low muscle mass, and sarcopenia in colorectal cancer patients
Berg, Hedda Beate; Alavi, Dena Treider; Beichmann, Benedicte; Pesonen, Maiju; Henriksen, Christine; Paur, Ingvild; Bøhn, Siv Kjølsrud; Lauritzen, Peter Mæhre; Blomhoff, Rune; Henriksen, Hege (Peer reviewed; Journal article, 2024)Background and aims: Low muscle strength, low muscle mass, and sarcopenia have a negative impact on health outcomes in colorectal cancer (CRC) patients. Different diagnostic modalities are used to identify these conditions ... -
Effect of a one-year personalized intensive dietary intervention on body composition in colorectal cancer patients: Results from a randomized controlled trial
Alavi, Dena Treider; Henriksen, Hege Berg; Lauritzen, Peter Mæhre; Zucknick, Manuela; Bøhn, Siv Kjølsrud; Henriksen, Christine; Paur, Ingvild; Smeland, Sigbjørn; Blomhoff, Rune (Peer reviewed; Journal article, 2023)Background and aims Changes in body composition may affect colorectal cancer (CRC) patient's risk of cancer recurrence, secondary cancer, and other chronic diseases. The suggested interventions for changes in body composition ... -
Halved contrast medium dose in lower limb dual-energy computed tomography angiography—a randomized controlled trial
Kristiansen, Cathrine Helgestad; Thomas, Owen Matthew Truscott; Tran, Thien Trung; Roy, Sumit K; Hykkerud, Dan L; Sanderud, Audun; Geitung, Jonn Terje; Lauritzen, Peter Mæhre (Peer reviewed; Journal article, 2023)Objectives To compare vascular attenuation (VA) of an experimental half iodine-load dual-layer spectral detector CT (SDCT) lower limb computed tomography angiography (CTA) with control (standard iodine-load conventional ... -
Indirect CT venography of the lower extremities: impact of scan delay and patient factors on contrast enhancement and examination quality
Tran, Thien Trung; Kristiansen, Cathrine Helgestad; Thomas, Owen Matthew Truscott; Roy, Sumit K; Haidl, Frans Felxi; Ashraf, Haseem; Kløw, Nils-Einar; Stavem, Knut; Lauritzen, Peter Mæhre (European Radiology;Volume 32, issue 11, Peer reviewed; Journal article, 2022-05-12)Objectives Indirect computed tomography venography (CTV) is often the next imaging modality for deep vein thrombosis (DVT) when sonography is inconclusive. Our aim was to investigate the impact of scan delay and patient ... -
Is a Single Nephrographic Phase Computed Tomography Sufficient for Detecting Urothelial Carcinoma in Patients with Visible Haematuria? A Prospective Paired Noninferiority Comparison
Galtung, Kristina Flor; Lauritzen, Peter Mæhre; Sandbæk, Gunnar; Bay, Dag; Ponzi, Erica; Baco, Eduard; Cowan, Nigel C.; Naas, Anca Michaela; Rud, Erik (Peer reviewed; Journal article, 2023)Background: There is uncertainty about the utility of multiphase computed tomog- raphy (CT) compared with single-phase CT in the routine examination of patients with visible haematuria (VH). Objective: To compare the ... -
