Diagnostic imaging and therapy in a case of myasthenia gravis associated with thymic hyperplasia.

The diagnostic approach to a patient with myasthenia gravis to verify the presence of thymic hyperplasia/thymoma is presented. The study of the mediastinal region was necessary. Mediastinal MRI showed the presence of a mass.

Post-processing of digital images.

Post-processing of bi- and three-dimensional images plays a major role for clinicians and surgeons in both diagnosis and therapy. The new spiral (single and multislice) CT and MRI machines have allowed better quality of images. With the associated development of hardware and software, post-processing has become indispensable in many radiologic applications in order to address precise clinical questions.

Imaging of small bowel tumors.

Small bowel tumors represent less than 25% of all gastrointestinal tumors and 1-2% of malignant tumors in general. However for their nonspecific clinical presentation, diagnosis is often late, because of the patient delay to contact the doctor and especially the doctor difficulty to advance the clinical suspicion and request the suitable clinicoinstrumental diagnostic tests. The radiologist plays a major role in early diagnosis, treatment and prognosis.
