Computerized axial tomography (or computed tomography) scan is an x-ray procedure which combines many x-ray images with the aid of a computer to create cross-sectional or three-dimensional images of internal organs and structures within the body.
May 12th, 2007. Computer-assisted diagnosis for early stage pleural mesothelioma: towards automated detection and quantitative assessment of pleural thickening from thoracic CT images
Conclusion: Results obtained so far indicate that our approach is able to assist physicians in the tedious task of finding and quantifying pleural thickenings in CT data. In the next step, our system will undergo an evaluation in a clinical test setting using routine CT data to quantify its performance.
November 23rd, 2006. CT-guided percutaneous transthoracic biopsy in the evaluation of undetermined pulmonary lesions
Gender, smoking, location, pleural tag, homogenous attenuation, cavitation, calcification, necrosis and air bronchogram did not differ significantly between benign and malignant nodules. This study shows that CT-guided PTB is a safe and effective procedure in the evaluation of undetermined pulmonary lesions.
September 30th, 2006. Early response evaluation in malignant pleural mesothelioma by positron emission tomography with [18F]fluorodeoxyglucose
Conclusion: The use of MR evaluated by FDG-PET in the assessment of treatment efficacy in MPM appears promising. Our observations need to be validated in a larger prospective series.

September 25th, 2006. An atypical presentation of thymoma with diffuse pleural dissemination mimicking mesothelioma
Here, we report a case of advanced thymoma mimicking malignant pleural mesothelioma, with circumferential encasement of the lung. A brief review of the literature with special reference to radiological imaging on thymoma also is presented.
July 19th, 2006. Imaging of pleural disease
The conditions covered include benign and malignant pleural thickening, pleural effusions, empyema and pneumothoraces. The relative merits of CT, MRI and PET in the assessment of these conditions and the role of image-guided intervention are discussed.

July 11th, 2006. 18-Fluoro-deoxy-glucose (15FDG) positon emission tomography (PET) for the evaluation of malignant pleural disease
SUV > 4 associated with a non-epithelial tumor is a sign of poor prognosis. For mesotheliomas, FDG uptake can be used to assess the effect of chemotherapy and determine whether patients are good responders or not.
June 14th, 2006. Preoperative Evaluation of Patients With Malignant Pleural Mesothelioma: Role of Integrated CT-PET Imaging
Specifically, CT-PET detects more extensive disease involvement than that shown by other imaging modalities and is particularly useful in identifying occult distant metastases. This article reviews aspects of imaging performed in the initial staging of patients with MPM according to the International Mesothelioma Interest Group staging system and will emphasize the appropriate role of CT-PET imaging in determining the T, N, and M descriptors.
June 9th, 2006. Peritoneal mesothelioma presented with bilateral hydronephrosis: a case report
Pathological diagnosis was peritoneal mesothelioma. Chemotherapy based on the pleural mesothelioma was done but not effective, she died 9 months after the first medical examination.
May 10th, 2006. Imaging before and after multimodal treatment for malignant pleural mesothelioma
Conclusions: CT, PET and CT-PET are indicated for diagnosis and, above all, for staging of MPM, in the selection of patients who might benefit from surgery after neoadjuvant therapy and also in identifying small recurrences and/or remote metastases. Being highly specific, PET is essential in the follow-up of patients undergoing chemoradiotherapy alone and/or surgery. Each imaging modality has its advantages and limitations, but their combined use is crucial in determining the most appropriate treatment options for patients with MPM.

May 5th, 2006. Pleural mesothelioma: imaging contribution
fr Abstract Imaging plays an essential role in management of patients of with pleural mesothelioma. In this article, we discuss the respective roles for ultrasonography, computed tomography, magnetic resonance imaging, and positon emission tomography for the diagnosis, staging, and postherapeutic evaluation of pleural mesothelioma.
April 25th, 2006. Computed tomography findings in 66 patients with malignant pleural mesothelioma due to environmental exposure to asbestos
8%) were the most common CT findings of MPM. Although none of these findings are pathognomonic for MPM, they may provide valuable clues for the differential diagnosis, at least in patients with a history of asbestos exposure.
March 24th, 2006. Variability in Mesothelioma Tumor Response Classification
Conclusion: The presentation of baseline scan tumor measurements affects measurements acquired on follow-up scans and could influence tumor response classification. The potential utility of semiautomated tumor thickness measurements was shown in the context of measuring tumor response.
February 9th, 2006. Computed tomographic characterization of malignant peritoneal mesothelioma
Conclusions: Malignant peritoneal mesothelioma by CT evaluation predominates in tumor mass within the central and pelvic portions of the abdomen. Minimal, moderate, and extensive small bowel enlargements were seen in roughly one-third of the patients. With the use of the Z-score and interpretative small bowel findings a radiologic characterization of this disease for primary radiologic diagnosis is possible.
January 27th, 2006. Integrated PET/CT: Current Applications and Future Directions
For prostatic cancer, choline derivatives may become useful radiopharmaceuticals. The published literature on the applications of FDG PET/CT in oncology is still limited, but several well-designed studies have demonstrated the benefits of PET/CT.
January 27th, 2006. Additional value of hybrid PET/CT fusion imaging vs. conventional CT scan alone in the staging and management of patients with malignant pleural mesothelioma
Conclusions: Our data show that (18)F-FDG PET/CT fusion imaging can play a relevant role in the staging and treatment planning of MPM patients.
January 9th, 2006. Magnetic resonance imaging in the evaluation of pneumonia
With parallel imaging techniques, MRI examination of the lungs can be performed with short periods of breath holding, which allow for sub-centimeter resolution in the z-axis. Especially for follow-up examinations in immunocompromised patients and, in some instances, for the staging of malignant diseases (malignant pleural mesothelioma, lung cancer, respectively), MRI is very promising and may contribute to a decrease in the radiation exposure of the patients.
November 21st, 2005. Use of imaging in the management of malignant pleural mesothelioma
In view of its pattern of growth, MPM is a challenging disease to image by any method, and it behaves quite differently from lung cancer. This review aims to highlight the practical aspects of assessing malignant pleural mesothelioma.
September 20th, 2005. Evaluation of Semiautomated Measurements of Mesothelioma Tumor Thickness on CT Scans
Conclusion: We have developed semiautomated methods to measure mesothelioma tumor thickness. The potential of these methods has been demonstrated through an observer study. We expect these methods to become important tools for the efficient quantification of tumor extent. Key Words: Computer-aided diagnosis (CAD); malignant pleural mesothelioma; tumor measurement; computed tomography; image processing

PET can provide both anatomic and metabolic information, especially in cases of extrathoracic and mediastinal nodal metastasis. Each imaging modality has its advantages and limitations, but their combined use is crucial in determining the most appropriate treatment options for patients with MPM.
March 1st, 2005. CT in differential diagnosis of benign and malignant pleural disease
