Predicting Mesothelioma Outcomes with FDG-PET: A New Model

Predicting Mesothelioma Outcomes with FDG-PET

Swiss doctors have created a new tool for predicting mesothelioma outcomes with FDG-PET scans.  FDG-PET scanning is a nuclear imaging technique. It gives doctors a non-invasive way to track the growth of pleural mesothelioma tumors.  The Swiss team analyzed multiple PET scans and CT scans from mesothelioma patients. They used a computer to look for commonalities in the scans. Then they used the information to create a computer model for predicting mesothelioma outcomes with FDG-PET. The model may help doctors and patients make better decisions about mesothelioma treatment in the future.  Imaging Studies for Mesothelioma Prognosis Pleural mesothelioma tumors occur on the pleural lining around the lungs. In the early stages, mesothelioma causes few symptoms. As mesothelioma tumors grow, they … Continue reading Predicting Mesothelioma Outcomes with FDG-PET: A New Model »

Tracking Mesothelioma Recurrence: FDG-PET/CT Versus CT

mesothelioma recurrence

FDG-PET/CT may be a more effective way to track malignant pleural mesothelioma recurrence than contrast-enhanced CT scanning.  That is the conclusion of cancer researchers with Japan’s Hyogo College of Medicine. The researchers focused on fifty patients who underwent radical surgery for pleural mesothelioma. Afterwards, doctors used both FDG-PET/CT and contrast-enhanced CT scans to track mesothelioma progression. Two experienced examiners assessed the cases. They concluded that FDG-PET/CT was more accurate than CT for diagnosing mesothelioma recurrence. Mesothelioma Recurrence After Surgery Pleural mesothelioma is one of the most difficult cancers to treat. It arises in the layers of the pleural membrane that surrounds the lungs. Mesothelioma tumors tend to grow and spread quickly. Treatments like chemotherapy, surgery, and radiotherapy can sometimes slow … Continue reading Tracking Mesothelioma Recurrence: FDG-PET/CT Versus CT »

FDG/PET Best for Mesothelioma Diagnosis and Prognosis

PET Scan

When it comes to diagnosing mesothelioma and predicting patient prognosis, Positron Emission Tomography (PET) using a radioactive tracer may be the most effective imaging modality. That’s the finding of a new study out of Japan. Mesothelioma is a fast-growing cancer that starts on the mesothelial membranes which line the chest cavity or wrap around the lungs and heart. It is caused by past exposure to asbestos, most often in an industrial setting. The greater the level of exposure, the greater the likelihood that mesothelioma will occur. Because it is highly resistant to conventional treatments, early diagnosis is critical. Unfortunately, mesothelioma can also be challenging to diagnose. If patient history and symptoms suggest mesothelioma, imaging modalities like computed tomography (CT) and X-rays can … Continue reading FDG/PET Best for Mesothelioma Diagnosis and Prognosis »

Mesothelioma Prognosis Accuracy Improves with PET/CT ‘Delayed Phase’

Detecting Mesothelioma with New CT Algorithm

More research has confirmed the value of FDG-PET/CT technology for predicting treatment response in mesothelioma – especially when the scan is conducted in two phases. Positron emission tomography (PET) is a nuclear medicine imaging technique that produces three-dimensional images of functional processes in the body.  When the molecule FDG (fluorodeoxyglucose, a type of sugar) is used as the tracer, PET allows doctors to ‘see’ metabolic processes as they are happening.  Because metabolism is often higher in cancer cells, FDG-PET has proven to be a useful tool for diagnosing mesothelioma, the asbestos-linked cancer.   When FDG-PET is combined with computed tomography (CT), another powerful imaging test, the resulting images contain even more potentially crucial diagnostic, staging and prognostic information for mesothelioma. Now, a study conducted in Japan … Continue reading Mesothelioma Prognosis Accuracy Improves with PET/CT ‘Delayed Phase’ »
