Bakanlığı ve uluslararası kurumlar hijyen kurallarını tanımlayan broşürler yayınladı. Bilgisayarlı tomografi (BT) görüntülerinde COVID-19 tanısında önemli olan akciğer bulgularının tanımlanmasıyla radyoloji bölümlerinde enfeksiyondan korunma önlemleri açıklanmıştır. Nükleer tıpta tanı ve tedavi işlemleri için (randevu vermek, hasta kabulü, görüntüleme ve tedavi işlemleri, dezenfeksiyon gibi) korunma önlemlerini içeren yayın yoktur. 18 F-florodeoksiglukoz pozitron emisyon tomografi/BT taramada COVID-19'u düşündüren BT bulguları hakkında iki yayın vardır. Hibrid görüntülerde saptanan bu akciğer bulguları akciğer tutulumunun erken tanısında faydalı olacaktır. Enfekte olgular asemptomatik olabilir ve farkında olmadan virüsü çevresindeki kişilere yayabilir. Öneri niteliğindeki bu kılavuz Nükleer Tıp kliniklerinde enfeksiyon riskini önlemek amacı ile hazırlanmıştır. COVID-19 salgını sırasında, personel uygun kişisel koruyucu ekipman kullanmalı ve hastalar klinik durumlarına göre elektif olgu olarak değerlendirilmelidir. COVID-19 açısından anket yapılmalıdır. Acil tedavi gereken kanser olgularında, COVID-19 test sonucuna göre radyonüklit tedavi (RNT) planlanmalıdır. Sonuç negatif ise RNT uygulanabilir. Sonuç pozitif ise veya semptomlar varsa, RNT ertelenmelidir. Görüntüleme işlemlerinden sonra, tarayıcılar ve oda yüzeyleri dezenfeksiyon konusunda uygun eğitim almış personel tarafından temizlenmelidir.

In February 2020, WHO named as Coronavirus Disease 2019 (COVID-19) and declared the pandemic on March 11, 2020. To prevent the spread of COVID-19, Ministry of Health of Republic of Turkey and international institutions have published documents defining hygiene rules. After the lung computerized tomography (CT) findings which are important in the diagnosis of COVID-19 are described, protection measures against infection were defined in radiology departments. There is no publication involving protection measures for diagnostic and therapeutic procedures in nuclear medicine (NM) (appointment, patient acceptance, imaging and treatment procedures, disinfection etc). There are two reports on CT findings suggesting COVID-19 in 18 F-fluorodeoxyglucose positron emission tomography/CT scan. These lung findings detected in hybrid images will be helpful in the early diagnosis of pulmonary involvement. Infected cases may be asymptomatic and can unintentionally disseminate the virus to surrounding people. This advisory guide has been prepared to avoid infection risk in NM clinics. During the COVID-19 outbreak, staff must use proper personal protective equipment and patients should be evaluated as the elective case according to clinical status. A questionnaire should be made for COVID-19. In cancer cases requiring urgent treatment, radionuclide treatment (RNT) should be planned accordin...
Objective: We aimed to evaluate the role of gated myocardial perfusion SPECT (MPS) and to investigate whether only the invasive coronary angiography (CAG) is sufficient in the diagnosis of the coronary artery disease (CAD) in women. Material and Methods: Sixty-four women (62±10 years) with known CAD were included in this study. They had echocardiography (ECHO), stress/rest gated MPS and invasive CAG. Coronary stenosis as of > 50 % in invasive CAG was accepted as significant. Gated MPS data were compared with invasive CAG and ECHO. Results: Invasive CAG results were abnormal in 34 patients, and normal in 30 cases. Myocardial ischemia was detected by gated MPS in 22/ 30 cases with normal invasive CAG, 6 had mild coronary stenosis in major coronary arteries ranging from 30% to 50% in invasive CAG. 16/ 22 women were diagnosed as metabolic syndrome according to MetSend Diagnostic Criteria and only 8 of 30 patients with normal invasive CAG had false positive MPS data on the reevaluation by a nuclear cardiologist.Conclusion: We think that invasive coronary angiography method is not sufficient alone in the diagnosis of CAD in women. Gated MPS study is recommended to achieve the final decision for myocardial ischemia in the cases with CAD and raw data must always be evaluated to avoid attenuation artifacts. Conflict of interest:None declared.
18F-FDG-PET/CT identified the primary tumor site well in 50% of our cases. We propose that 18F-FDG PET/CT imaging may help to accurately detect malignant lesions in patients with unknown primary tumors.

INTRODUCTIONThe H pylori infection is one of the most common chronic infections in humans [1,2] . The H pylori colonizing on the surface of the upper gastrointestinal mucosa is an interesting cause of active chronic gastritis and duodenitis or even gastric cancer worldwide [2][3][4][5][6][7] . The presence of H pylori infection could predispose to various disorders [8][9][10][11][12][13][14] . Dental disease might be associated with a higher recurrence of H pylori infection [9] . Some investigators have recently demonstrated the evidences that H pylori infection induced atherosclerosis and that H pylori-anti-heat-shock protein antibodies have been related to the prevalence of diseases such as coronary artery disease or cerebral infarction, resulted from atherosclerosis [10,11] . The H pylori may play a role in the pathogenesis of slow coronary flow via the elevation of homocysteine, and/or a possible disturbance in its metabolism [12] . The H pylori is present in about 67%-100% of duodenal ulcer patients and 13%-61% of normal population [15] . The H pylori infection can be diagnosed by invasive techniques requiring endoscopy and biopsy (eg, histological examination and culture) and by noninvasive techniques such as serology, urea breath test or detection of H pylori
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
