PURPOSE To investigate the fusion of pelvic magnetic resonance imaging (MRI) and fluorodeoxyglucose positron emission tomography (PET) for assessment of locoregional extension and nodal staging of cervical cancer. METHODS PET/computed tomography (CT), MRI, and non-fused and fusion of PET and MRI for assessing the extent of the primary tumor and metastasis(More)
To review established magnetic resonance (MR) criteria and describe a new MR finding for the diagnosis of invasive placenta praevia. A retrospective review of prenatal MRI examinations of 65 patients (median age: 35 years) who underwent MR for the screening of invasive placenta praevia. All MRIs were performed on a 1.5-T unit, including axial, coronal and(More)
PURPOSE To investigate the diagnostic value of retrospective fusion of pelvic MRI and (18)F-fluorodeoxyglucose ((18)F-FDG) PET images for assessment of locoregional extension and nodal staging of endometrial cancer. MATERIALS AND METHODS Thirty patients with biopsy-proven endometrial cancer underwent preoperative contrast-enhanced PET/CT (PET/ceCT) and(More)
To evaluate the accuracy of PET/CT using 18F-fluorodeoxyglucose (FDG) with IV contrast for suspected recurrent head and neck squamous cell carcinoma (HNSCC). One hundred and seventy patients previously treated for HNSCC underwent PET/CT, consisting of non-contrast-enhanced and contrast-enhanced CT, to investigate suspected recurrence. Diagnostic performance(More)
We propose a methodology for animating complexmodels based on simplexmesh represen tation and deformation A simplex mesh is characterized by a connectivity between vertices of three and can be obtained by duality from a triangulation In addition to their generality of representation simplex meshes have a compact and unambiguous shape description related to(More)
PURPOSE To ascertain the role of respiratory-gated PET/CT with (18)F-fluorodeoxyglucose ((18)F-FDG) for accurate diagnosis of liver metastasis. MATERIALS AND METHODS Forty patients with suspected liver metastasis underwent conventional whole-body PET/CT scan initially, followed by respiratory-gated PET/CT scan covering the liver. Visual detectability(More)
A case of cutaneous infection by Exophiala jeanselmei is reported. The patient was a 45-year-old Japanese female. Her skin eruption consisted of a group of erythematous papules on her left cheek to which corticosteroid had been topically applied for nearly 10 years. Histopathologically, a granuloma formation was noted in the dermis within which were many(More)
A variety of different tumors can arise from any of the tissues present in the retroperitoneum, and they exhibit a wide range of pathologic types. Although computed tomography (CT) and magnetic resonance imaging (MRI) can demonstrate important characteristics of these tumors, diagnosis is often challenging for radiologists. The purpose of this pictorial(More)
PURPOSE To assess the clinical value of retrospective image fusion of neck MRI and (18)F-fluorodeoxyglucose ((18)F-FDG) PET for locoregional extension and nodal staging of neck cancer. MATERIALS AND METHODS Thirty patients with carcinoma of the oral cavity or hypopharynx underwent PET/CT and contrast-enhanced neck MRI for initial staging before surgery(More)
