Introduction: Digital radiography has a major role in nowadays healthcare system so radiation protection (justification and optimization) is important in this field. Many related organizations to protection suggested to establish national and regional diagnostic reference level for medical procedures. Reference levels are typically set at the 75th percentile of the dose distri...

We studied the rate of incidental detection of lung carcinomas and its effect on long-term survival in a nationwide cohort of patients operated for nonsmall cell lung cancer (NSCLC). All patients operated for NSCLC in Iceland during 1991–2010 were included. Demographic and clinicopathological features were compared in patients diagnosed incidentally using chest radiography or computed tomograph...

Exact localization of foreign body is important for planning the treatment required for its retrieval without much tissue damage. Plain film radiography is the initial screening modality used for the detection of suspected foreign body. However, about one-third of all the foreign bodies are missed in the initial radiographic examination. In case of a wooden foreign body, only 15% are well-visua...

A previously healthy 35-year-old Swiss woman presented with fever, headache, and myalgia for three days. Symptoms began on the final day of travel in Colombia. Abdominal examination revealed a positive Murphy sign. Laboratory results at presentation are shown in Table 1. Abnormal findings included a thrombocytopenia (121,000/mm), an elevated total bilirubin (48 μmol/liter), and high alkaline ph...

PURPOSE The objectives of this study were to survey the radiographic exposure parameters, to measure the patient doses for intraoral dental radiography nationwide, and thus to establish the diagnostic reference levels (DRLs) in intraoral dental X-ray examination in Korea. MATERIALS AND METHODS One hundred two intraoral dental radiographic machines from all regions of South Korea were selected...

A 15-year-old boy presented with a gunshot wound in the left cerebellar hemisphere. He was confused and left cerebellar signs were noted. The patient underwent the first surgery for debridement of the entry wound in the left parietal region and second surgery to remove the bullet. However, the bullet could not be located via a left unilateral suboccipital craniectomy in the park bench position,...

general practitioners are more capable of discriminating mild disease from normality than they admit to in a referral letter. Only one third of the children had an investigation. This is contrary to suggestions that investigation of every heart murmur is mandatory. In fact, the diagnosis of quiet asymptomatic murmurs is unlikely to be greatly helped by chest radiography or electrocardiography, ...

Nodular fasciitis (NF) is a rare fibroblastic proliferative lesion, characterized clinically as a solitary mass of hardened and slightly painful on palpation, fast growing and no gender preference. The objective of this study is to report the case of a patient with NF in third finger of left hand, describe the findings of plain radiography, computed tomography and magnetic resonance imaging and...

abstract introductiion. there are a lot of edentulous patients who need complete dentures in any society. one of the most important problems of edentulous patients is remaining dental lesions. atrophy of maxillary or mandibular bone, infections abcesses, tumors and so on are among some other problems. in this study we tried to evaluate the panoramic radiography in order to detect these problems...
