Future Perspectives of Multislice CT

T.Flohr write on first paragraph of this chapter on page of 25, Owing to its ease of use its widespread availability, general purpose CT continues to involve into the most widely used diagnostic modality for routine examination especially in emergency situations or for oncological staging. CT primarily provides morphological information. In combination with their modalities , however , functional and metabolic information can also be obtained. There fore . combined system for obtain comprehensive structural and functional diagnoses will gain increasingly importance in the near future . major clinical application of PET/CT so far have been oncological staging and the search for inflammatory foci. CT can add sensitivity to PET, as certain small lesions (eg lung nodules) may not be visualized on PET alone, and PET adds specify to CT because to CT because in terminate lesions seen on CT can often diagnosed unequivocally as benign or malignant using PET information. Occults sites of cancers recurrence can be identified to guide subsequent treatment in many patient. If the respective CT system is a state of the art MSCT providing submillmeter collimation and fast gantry rotation, the additional potential for co prehensile cardiac examination is opened. While CT deliver morphological information about stenosis or plagues in coronaries, PET can add assessment on cardiac function, e.g, by determining the hemodynamic relevance of a stenosis. The diagnostic benefit of PET/CT Scan for cardiac applications is currently being evaluated . Other potential application include PET/CT guided biopsy or the use of PET/CT in radiation therapy planning to reduce the irradiated.

Case study illustrating the clinical performance of PET-CT . MPR with superimposed PET images of a patient with renal cancer. A mediastinal lymph node metastasis (arrow) is identified by increased focal uptake of the FDG tracer (courtesy of Indiana University , Indianapolis , USA).
