Extrahepatic Tumors: A Case Study

It was recorded that 12 out of 35 patients, suffered from extrahepatic tumour. This was revealed by PET/CT combined and by CT scan single-handedly. The extrahepatic tumours in two of the patients were not detected by PET and PET/CT; those were recorded to have node of 2 –cm lymph in the hepatoduodenal ligament. It is furthermore, true that both forms of the scans (CT and PET/CT) reported extrahepatic tumour in patients that did not have it at all. The CT scan reported it in 3 out of 23 patients, and PET/CT did in 1 out of 23 patients. The scan of PET/CT gave a hint of the tumour outside the liver 11 of the case, of those 10 were positives and one was false positive and CT suspected it in 10 of the cases, of those 7 were positives and 3 were …show more content…
In order to gauge as to which should be used to diagnosis metastasis – 116 patients were asked to undergo both MRI and pet/ct. thus the comparison was based on the results of the tests. The findings of the final outcomes showed that the totals of 614 lymph nodes were detected in 116 patients. However, of those 274 were negative and 340 were found out to be positive nodes. It was surprising to many of the medical profession as the PET/CT was concluded to be more sensitive, specific and accurate in diagnosing node (Rappeport, et, al., 2009). Furthermore, it was found out to be 93.2%, 98.2% and 95.3% respectively as per different findings. In constant, the accuracy of MRI was 88.8%, 91. % and 89.10% respectively according to different findings. However, the findings of both technologies had significant statistical difference between them. It was concluded thus PET/CT has been more effective than MRI in diagnosing metastasis. Moreover, assessment of the false positive and false negative in PET/CT scan is affected b few of variables, such as, node with large areas of necrosis, inflammatory hyperplastic node and node in
