A recent draft has been published by The U.S. Preventive Services Task Force (USPSTF) that recommends the following: Screening for abdominal aortic aneurysm (AAA) by ultrasonography in men ages 65 to 75 years who have ever smoked. The USPSTF recommends that clinicians selectively offer screening for AAA in men ages 65 to 75 years who […]
Thyroid nodules are very common and a small percentage of these are malignant. Ask 10 thyroid specialists about their approach to biopsy and diagnosis and you will get 10 different approaches. All will be rational and based on reasonable scientific data and on experience. The different approaches arise because the research is varied in its […]
EULAR Recommendations for the Use of Imaging of the Joints in the Clinical Management of Rheumatoid Arthritis These evidence based recommendations were developed by the European League Against Rheumatism (EULAR) based on a comprehensive review of publications relating to imaging in RA was carried out and 199 studies met sufficient criteria to be included in the […]
Hyperparathyroidism is most commonly due to adenomas or carcinomas. These can frequently be detected with dual phase Sestamibi scans. The sensitivity for detection is poor with planar and SPECT imaging (60-80%) but with the advent of SPECT-CT much higher sensitivities have been achieved (>85%). Multi-glandular disease is uncommon but paradoxically more difficult to detect with all modalities. Now with […]

This middle aged female was referred with shortness of breath and a CXR reported as showing oligaema in the left upper zones that could indicate pulmonary embolism. The reconstructed planar lung scan showed a large matched defect corresponding to the left upper lobe. The SPECT-CT scan shows a large airspace is responsible for the abnormality -most […]
Nuclear Medicine Update: Dr Iain talks about the value of SPECT-CT in bone scanning “Nuclear Medicine functional imaging is now directly combined with CT anatomical scanning to create SPECT-CT. It is the first technology to combine the power of SPECT with the precision of diagnostic multi-slice-CT. It makes it possible to pinpoint the exact location, […]
