چکیده
iv administration of USPIO C: Axial DW-MRI (b 1000) post USPIO. No significant SNR decrease (<20%) after USPIO in an obturator interne lymph node on the left side (large arrow on A and B) indicative for metastasis. Fig 1C shows the corresponding high intensity in DW-MRI after USPIO confirming metastasis. On the right side (smaller arrow on A and B) a normal lymph node with a significant SNR decrease after USPIO (A vs. B) is visible. This normal lymph node is not detectable on the DW-MRI due to susceptibility effects following USPIO uptake. Only malignant lymph nodes remain hyperintense on the DW-MRI sequences facilitating the reading. USPIO enhanced diffusion MRI increases the diagnostic confidence for detection of pelvic lymph node metastases in patients with bladder or prostate cancer

arrow). B (middle): Identical axial plane representing the ADC map. The mean ADC of the lymph node (black arrow) was measured with 78 x 10-5 mm/sec. C (right): Axial 3D T1-w SPACE reconstruction allowing to match the hyperintensive structure with a suspicious lymph node, which was correctly classified as positive from all readers. Size of the metastasis: 2mm x 2mm. Diagnostic Accuracy of Diffus...
متن کاملEndoscopic-Ultrasound-Guided Tissue Sampling Facilitates the Detection of Local Recurrence and Extra Pelvic Metastasis in Pelvic Urologic Malignancy
Pelvic lymph node dissection is the gold standard for assessing nodal disease in prostate or bladder cancer and is superior to CT, MRI and PET staging. Endoscopic ultrasound (EUS) provides an alternative, less invasive method of cytohistologic material acquisition, but its performance in pelvic urologic malignancy is unknown. Therefore, our aim was to evaluate the diagnostic accuracy of EUS gui...
متن کاملDiagnostic performance of USPIO-enhanced MRI for lymph-node metastases in different body regions: a meta-analysis.
OBJECTIVES USPIO (ultrasmall superparamagnetic iron oxide contrast agent) MRI was a promising imaging modality in the detection of lymph-node metastases. And this meta-analysis is performed to compare the diagnostic accuracy of USPIO-enhanced MRI with non-enhanced MRI, USPIO-enhanced MRI in various body regions, and postcontrast alone for diagnosis of lymph-node metastases. METHODS A comprehe...
متن کاملMolecular and Functional Imaging for Detection of Lymph Node Metastases in Prostate Cancer
Knowledge on lymph node metastases is crucial for the prognosis and treatment of prostate cancer patients. Conventional anatomic imaging often fails to differentiate benign from metastatic lymph nodes. Pelvic lymph node dissection is an invasive technique and underestimates the extent of lymph node metastases. Therefore, there is a need for more accurate non-invasive diagnostic techniques. Mole...

AIM In this feasibility study we investigated whether magnetic resonance imaging (MRI) with ultrasmall superparamagnetic iron oxide (USPIO) can be used to identify regional and distant lymph nodes, including mediastinal and celiac lymph node metastases in patients with oesophageal cancer. PATIENTS AND METHODS Ten patients with a potentially curative resectable cancer of the oesophagus were el...
