BACKGROUND The study purpose was to assess the predictive value of 2-[fluorine-18]fluoro-2-deoxy-D-glucose (FDG)-positron emission tomography (PET)/computerized tomography (CT) metabolic response after a single course of chemotherapy in patients with metastatic colorectal cancer (mCRC). PATIENTS AND METHODS FDG-PET/CT scans were carried out at baseline(More)
PURPOSE OF REVIEW Functional imaging including single photon emission computed tomography, PET and MRI techniques in head and neck squamous cell cancer allows disease characterization beyond structure and morphology. RECENT FINDINGS In patients without clinical signs of lymph node involvement, sensitivity of fluoro-2-deoxy-D-glucose PET is only 50%. This(More)
BACKGROUND AND PURPOSE To prospectively compare the effectiveness of time-of-flight (TOF) and contrast-enhanced (CE) MR angiography (MRA) with that of digital subtraction angiography (DSA) to assess immediate intracranial aneurysm occlusion after selective embolization. METHODS From August 2006 to March 2007, 33 consecutive patients with 40 aneurysms were(More)
BACKGROUND Only human epidermal growth factor receptor (HER)2 status determined by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) has been validated to predict efficacy of HER2-targeting antibody-drug-conjugate trastuzumab emtansine (T-DM1). We propose molecular imaging to explore intra-/interpatient heterogeneity in HER2 mapping(More)
UNLABELLED In PET-based patient monitoring, metabolic tumor changes occurring between PET scans are most often assessed visually or by measuring only a few parameters (tumor volume or uptake), neglecting most of the image content. We propose and evaluate a parametric imaging (PI) method to assess tumor changes at the voxel level. METHODS Seventy-eight(More)
2533 Background: Reliable early assessment of response would help identify active treatments and avoid unnecessary side effects. Our hypothesis was that FDG-PET metabolic changes 2 weeks after the first dose of chemotherapy predict standard morphological response. METHODS 45 mCRC patients undergoing 1st or 2nd-line chemotherapy are planned to be included(More)
Medical oncology needs early identification of patients that are not responding to systemic therapy. 18F-Fluorodeoxyglucose (FDG) positron emission tomography (PET) performed before and early during treatment has been proposed for this purpose. However, the best way to assess the change in FDG uptake between two scans has not been identified. We studied(More)
A 71 year old man presents with a high and low hemorrhage with no signs of associated shock. Endoscopy shows a laceration of the cardia (Mallory-Weiss syndrome). The low hemorrhage is attributed to a left colic lesion that appears to be an ischemic colitis. Colonoscopy in addition to baryum enema is useful in the differential diagnosis of colon lesions.
There is a limited understanding of the normal function of the pterygoïdeus proprius muscle and the role that this muscle may have in temporomandibular disorders. Despite a well-described anatomical in-vitro approach to this muscle, there are still difficulties in investigating the fossa pterygopalatina. This study reveals an alternative in-vivo approach by(More)
