There are several significant differences in GFR and ECV between healthy men and women.

Upper gastrointestinal symptoms have a poor clinical specificity to the actual rate of gastric emptying on scintigraphy. Diarrhoea as a symptom does not appear to be associated frequently with RGE, but our results confirm its relationship with hypoglycaemia. The majority of patients with a rapid emptying on gastric-emptying scintigraphy have no identifiable cause for an accelerated motility. Scintigraphic gastric-emptying studies provide a reliable and noninvasive method of investigation in patients where conventional investigations have failed to establish the cause of upper gastrointestinal dysfunction.

Despite changes in disease spectrum and advances in investigational techniques, our results suggest that (111)In-leucocyte scintigraphy is still a useful technique in establishing the cause of FUO. A higher PPV of this test in post-operative situations makes it especially applicable in this category of patients. Equally, the higher NPV in patients with spontaneous FUO virtually excludes infection/inflammation. Finally, a higher pre-test probability based on the radiological tests seems to be important in the optimal use of leucocyte imaging.

Primary hepatic lymphoma is extremely rare. Although the utility of fluorodeoxyglucose (FDG)-positron emission tomography (PET) for imaging extranodal lymphoma has been reported, there is very little literature describing its use in primary hepatic lymphoma. This case report demonstrates the effect of FDG-PET/computed tomography (CT) in a case of unifocal primary hepatic lymphoma and its usefulness in the assessment of treatment response.
