PURPOSE: Detecting a recurrence after lung radiofrequency ablation (RFA) is based on a group of arguments that include CT, positron emission tomography (PET-CT) at 3 months and clinical patient follow-up. There is no one examination that is absolutely reliable. Recurrences are diagnosed tardily, when the cancers are locally extended, or when the patients are metastatic. The purpose of this article is to investigate the utility of dual-energy computed tomography (DECT) in order to assess therapeutic responses to RFA for lung neoplasia...

A 61-year-old woman noticed a right neck lump in October 2001. Fine needle aspiration showed follicular neoplasm, adenoma versus carcinoma. The ultrasound scan showed a solid mass of maximum dimension of 3.7 cm. She had a right thyroid lobectomy and isthmectomy in January 2002 (first surgery). The tissue specimen showed a 4.5 cm Hurthle cell carcinoma (HCC) with vascular invasion. There were no capsular invasion, extra-thyroidal extension, or margin involvement. A completion left lobectomy (second surgery) was performed two weeks later...

The clinical use of Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) has proven to be a strong diagnostic tool in the field of neurology. The reliability of these methods to confirm clinical diagnoses has guided preclinical research to utilize these techniques for the characterization of animal disease models. Previously, we demonstrated that an endothelial cell-specific ablation of the murine Serum Response Factor (Srf(iECKO)) results in blood brain barrier (BBB) breakdown and hemorrhagic stroke...

Primary malignant melanoma of the gastrointestinal tract is extremely rare. A 35-year-old man presented with complaints of abdominal pain and weight loss. Contrast enhanced computed tomography showed a large mass involving the duodenum and the superior mesenteric vessels. Upper gastrointestinal endoscopy demonstrated a large, friable mass along the duodenal wall and biopsy was suggestive of malignant melanoma. A detailed physical examination and whole body imaging (positron emission tomography and computed tomography) did not reveal any other lesion...

INTRODUCTION: Treating ventricular tachycardia (VT) in patients with cardiac sarcoidosis (CS) is challenging as patients present in different phase of the disease (inflammatory, scar or sometimes both). A customized approach to treatment is required for better outcomes. We describe our experience in the management of VT in CS based on the phase of the disease. METHODS AND RESULTS: Patients were considered to have myocardial inflammation if there was an increased myocardial (18) Fluoro Deoxy Glucose (FDG) uptake in PET-CT scan of the chest (n=14)...

Radiation therapy plays an important role in the management of both limited stage and extensive stage small cell lung cancer. For limited stage disease, there has been a trend toward reduced size of thoracic radiation fields, which has the potential to reduce toxicity. FDG-PET staging helps make this possible by more accurately identifying areas of nodal and metastatic involvement. Trials have demonstrated similar outcomes using a range of radiation fractionation schedules, allowing flexibility in individualizing treatment...

BACKGROUND: Treatment of spinal metastatic lesions by radiofrequency ablation (RFA) before cementation can potentially help in local tumor control and pain relief. This is often limited by access and tumor location. This study reports multicenter clinical and imaging outcomes following targeted RFA (t-RFA) and cement augmentation in neoplastic lesions of the spine. MATERIAL AND METHODS: A retrospective multicenter study of 49 patients with 72 painful vertebral lesions, evaluated for clinical and imaging outcomes following RFA and cement augmentation of spinal metastatic lesions, was undertaken...

The theranostic sodium iodide symporter (NIS) gene allows detailed molecular imaging of transgene expression and application of therapeutic radionuclides. As a crucial step towards clinical application, we investigated tumor specificity and transfection efficiency of epidermal growth factor receptor (EGFR)-targeted polyplexes as systemic NIS gene delivery vehicles in an advanced genetically engineered mouse model of pancreatic ductal adenocarcinoma (PDAC) that closely reflects human disease. PDAC was induced in mice by pancreas-specific activation of constitutively active KrasG12D and deletion of Trp53...

Hepatocellular carcinoma is the most common primary liver malignancy. Liver transplantation has been a successful therapy for selected patients with hepatocellular carcinoma. Since 1996, Milan criteria have been universally recognized as the guidelines for selecting patients with hepatocellular carcinoma for orthotopic liver transplantation. However, the simple use of tumor size and number has been insufficient to indicate the biologic features of hepatocellular carcinoma and to predict the risk of tumor recurrence...
