Diagnostic CT Scan for Mesothelioma: More is Better

diagnostic ct scan

A new report out of the UK suggests that a thorough diagnostic CT scan for pleural mesothelioma should include images of the abdomen and pelvis, as well as the chest.  When a person goes to the doctor with early signs of malignant pleural mesothelioma, a CT scan of the chest is often the next step in making a diagnosis. CT scans create a 3-dimensional image of internal organs, making it easier to spot mesothelioma tumors.  But a research team led by the University of Bristol says a diagnostic CT scan that shows only the chest might miss mesothelioma tumors in other areas. How a Diagnostic CT Scan Works CT stands for computerized tomography. CT scanning is an advanced type of … Continue reading Diagnostic CT Scan for Mesothelioma: More is Better »

Invasiveness of Peritoneal Mesothelioma: MRI Beats CT for Assessment

invasvieness of peritoneal mesothelioma

New research shows MRI beats CT when it comes to measuring the invasiveness of peritoneal mesothelioma. Scientists from several of the top US cancer centers ran the study. It included nearly 500 mesothelioma patients and appears in the journal Clinical Colorectal Cancer.  The study shows that the invasiveness of peritoneal mesothelioma is more visible on MRI than it is on CT. The news could make a difference in how doctors plan peritoneal mesothelioma treatment.  Peritoneal Cancer Index and Mesothelioma Peritoneal mesothelioma cancer grows on the peritoneal membrane lining the abdomen. Like all forms of mesothelioma, it usually comes from exposure to asbestos. Peritoneal mesothelioma accounts for about a fifth of all mesothelioma cases.  Doctors assess the invasiveness of peritoneal mesothelioma … Continue reading Invasiveness of Peritoneal Mesothelioma: MRI Beats CT for Assessment »

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 »

Talc Pleurodesis Patients Need Alternate PET/CT Scan for Mesothelioma

PET/CT scan for mesothelioma

Certain patients may get more benefit out of an alternate type of PET/CT scan for mesothelioma. Positron emission tomography (PET) is a common tool for diagnosing mesothelioma. It is also used to monitor the effectiveness of mesothelioma treatments. Doctors often combine PET with computed tomography (CT) for an even clearer picture of mesothelioma progression. Typically, a PET/CT scan for mesothelioma involves injection of a tracer called FDG (fluorodeoxyglucose). But it turns out that PET/CT scans with this tracer do not work well for all mesothelioma patients. A new Japanese study suggests that mesothelioma patients who have had a procedure called talc pleurodesis should consider a different kind of PET/CT scan instead. How Does Talc Pleurodesis Impact PET/CT Scan for Mesothelioma? … Continue reading Talc Pleurodesis Patients Need Alternate PET/CT Scan for Mesothelioma »
