Can nuclear medicine procedures affect CT scans?

In brief: Not usually

Not usually nuclear medicine affecting ct but the opposite.
However ct scan with intravenous iodine contrast materials can affect thyroid scans and thyroid uptake. Renal GFR studies using glofil with i125 are also affected by iodine contrast of ct.

In brief: No

The answer is no.
A CT scan uses an external source of radiation (X-rays) while nuclear medicine scans use gamma radiation ( coming from within your body) to generate a images. Often times the two are combined like when a SPECT/CT or PET/CT scan is done.

In brief: No...

Nuclear medicine studies will not directly affect CT scans however depending on the half life and energy of the radiotracer, some CT technologists do not want to be exposed to the nuclear radiation which is still being emitted from the patient if the CT is performed immediately after the nuclear study.
