When having a pet scan, is the CT scan that used in conjunction good enough to diagnose all tumors?

In brief: Good but not all

It is good to have ct in conjunction with pet scan because ct provides more resolution.
It helps the radiologist correlate signals seen on pet scan with actual anatomy precisely. However, no test is perfect, so pet/ct is not able to diagnose all tumors. But pet/ct can diagnose many types.

In brief: No.

The ct is not good enough.
When it is combined with the pet scan it is very good.

In brief: Not always

Usually CT associated with PET varies in resolution.
Higher resolution usually more radiation dose to patient. Usually resolution good enough to localize structure causing increased metabolism. Usually associated CT is without intravenous contrast. PET can localize lesion for biopsy or surgery. If more detail needed once lesion localized many times MR for tissue characteristics is usualized
