In conclusion : MRI is- superior to CT to demonstrate the anatomy of the pituitary gland. The patient with the isolated DI, with variation in polyuria, shows no identifiable antehypophyseal tissue. It is our opinion that PESS in children as defined by CT scan, groups heteroqenous anatomical ...

CT Scan, MRI and PET Scans…What are the differences? CT, MRI and PET scans are all diagnostic tools to non-invasively (non-surgically) look inside the body. They are all based on the fact that certain things happen to atoms in our bodies when they absorb energy. Resonance refers to th...

(MRI), and seek to guide clinicians only to refer for imaging based on specific indications. Despite this, several studies show an increase in the use of MRI among patients with low back pain and an imbalance between appropriate versus inappropriate use of MRI for low back pain.” In this ...
Accurate TB delineation on the radiotherapy planning CT scan after lumpectomy is important for both TB boost irradiation and APBI. However, in radiotherapy practice, there is no gold standard to validate the accuracy of our target volume delineation after lumpectomy. As an alternative, consensus ...
22 of 23 recruited patients were analysed because one patient discontinued before completion of the whole-body scan. Mean exposure to ionising radiation was 12·5 mSv (SD 4·1) for 18F-FDG PET/CT compared with zero for whole-body diffusion-weighted MRI. 18F-FDG PET/CT detected 163 of 174...
