The aim of the present study was to assess retrospectively the additional value of positron emission tomography (PET)/computed tomography (CT) in the detection of unexpected extrapulmonary lesions in the staging of patients with a malignant pulmonary lesion in comparison with CT and PET used alone. A total of 217 patients with a pathologically proven lung tumour underwent PET/CT. CT, PET and PE...

Objective: To evaluate the value of Gallium-67 single-photon emission computed tomography/computed tomography in the diagnosis and monitoring treatment response of malignant otitis externa. Methods: Eight patients underwent 12 Gallium-67 single-photon emission computed tomography/computed tomography scintigraphy for eight suspected malignant otitis externa and were subsequently subjected to vis...

PURPOSE We performed this network meta-analysis to compare the diagnostic value of 4 imaging methods (magnetic resonance imaging, positron emission tomography, computed tomography, and diffusion-weighted imaging) for diagnosing lymph node metastases in cervical cancer. METHOD Diagnostic tests regarding different imaging methods to diagnose lymph node metastases in cervical cancer were retriev...

OBJECTIVES Routine application of positron emission tomography/computed tomography (PET/CT) for pancreatic cancer staging remains a controversial approach. The purpose of this study was to reassess the clinical impact of PET/CT for the detection of distant metastasis of pancreatic cancer. METHODS From January 2006 to June 2009, 125 patients with histologically proven pancreatic cancer that ha...

Diagnosis of cardiac involvement in sarcoidosis is challenging and usually relies on a combination of clinical findings and imaging abnormalities. The case of a 53-yr-old female is described who presented with ventricular tachycardia and suspected angiosarcoma involving the right atrium and superior vena cava. A combination of magnetic resonance imaging and (18)F-2-fluoro-2-deoxyglucose-positro...

Imaging options There are several imaging options capable of identifying and defining breast cancer. These include X-ray mammography, ultrasound, computer tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET). Newer modalities such as positron emission mammography (PEM) or near infrared spectroscopy (NIRS), recently or soon to be available in clinical practice...

I collect emission line profiles for seven intermediate polars, phase-resolved over the spin cycles. I then present the first systematic application of Doppler tomography to the spin cycles, with the aim of investigating whether spin-cycle tomography is a useful diagnostic tool. Four stars show line emission from material falling onto both magnetic poles of the white dwarf, but three others sho...

We treated a patient with inflammatory pseudotumor of the mediastinum that exhibited high uptake of fluorodeoxyglucose on positron emission tomography. A 69-year-old male patient was diagnosed with a mass measuring 70 mm in diameter in the anterior mediastinum as revealed by computed tomography. The lesion showed strong uptake of 18-fluorine fluorodeoxyglucose with a maximum standardized uptake...
