conditions must also be considered in the differential diagnosis. Arterial aneurysmal rupture is the most common cause of death in Behçet’s disease [3]. Rupture may occur in 60% of arterial aneurysms and has a varying range of fatal outcome [7]. According to Urayama et al., the mortality rate in patients with arterial aneurysm is about 60% [9]. Furthermore, 50% of patients with pulmonary artery...

Introduction: Unfolding X-ray spectrum is a powerful tool for quality control of X-ray tubes. Generally, the acquisition of the X-ray spectrum in diagnostic radiology departments is complicated and difficult due to high photon flux. Measurement of x ray spectra using radiation detectors could not be performed accurately, because of the pulse pile up. Therefore, indirect methods...

Dear Sir,?The paper on ' Conservative surgery in malignant disease' by Dr. T. Howard Somervell, appearing in your March issue, opens up several avenues of partly criticism and partly controversy. Dr. Somervell gives a sarcoma patient ' a full course of deep x-ray therapy' to the growth and its immediate neighbourhood before operation. This course consists of five minutes of 5 milliamps at a 5-i...

Outpatient drainage therapy is generally indicated for spontaneous pneumothoraces. A 63-year-old man, who had been attacked by a bull sustaining injuries on the right side of his chest, was referred to the emergency room with dyspnea. His chest X-ray showed a small pneumothorax. The next day, a chest X-ray demonstrated that his pneumothorax had worsened, although no hemothorax was identified. O...

Conventional photodynamic therapy (PDT)'s clinical application is limited by depth of penetration by light. To address the issue, we have recently developed X-ray induced photodynamic therapy (X-PDT) which utilizes X-ray as an energy source to activate a PDT process. In addition to breaking the shallow tissue penetration dogma, our studies found more efficient tumor cell killing with X-PDT than...
