1*BOWEL PREPARATION OF THE PATIENT HELPS TO REDUCE 67Ga ACTIVITY WITHIN THE BOWEL. A DELAYED ABDOMINAL VIEW AT 96 HOURS WILL AID IN INTERPRETING ABDOMINAL ACTIVITY*

2*IMAGING WITH 67Ga EARLIER THAN 48 HOURS MAY SHOW SOME RENAL UPTAKE, AND SHOULD NOT BE REPORTED AS RENAL INFECTION. HOWEVER, RENAL UPTAKE AT 72 HOURS IS ALWAYS ABNORMAL*

3*LUNG ACTIVITY SHOULD CLEAR DURING THE STUDY. IF IT DOSE NOT, THE WBC MAY HAVE BEEN DAMAGED (ACTIVATED) DURING THE LABELLING PROCESS*

4*WHEN CONSIDERING THE DIFFERENTIAL DIAGNOSIS BETWEEN PULMONARY SARCOIDOSIS AND TUBERCULOSIS, ASYMMETRICAL TRACER UPTAKE IS AN INDICATION OF TUBERCULOSIS. WITH SARCOIDOSIS, HILAR OR DIFFUSE LUNG INVOLVEMENT IS MOST OFTEN SEEN, BUT THESE ARE ONLY GENERAL GUIDELINES*

5*THE FINDING OF INCREASED UPTAKE IN LACRIMAL AND PAROTID GLANDS IS STRONGLY SUGGESTIVE OF SARCOIDOSIS, ALTHOUGH NOT DIAGNOSTIC*

6*WHEN TRACER UPTAKE IS SEEN IN THE ABDOMEN ON THE FIRST 67Ga SCAN (USUALLY 48 HOURS), THE STUDY SHOULD BE REPEATED AT 72 HOURS, AND EVEN 96 HOURS IF NECESSARY, TO DISTINGUISH NORMAL BOWEL FROM FOCAL DISEASE*

7*RADIATION SIALITIS, ESPECIALLY INVOLVING THE SUBMANDIBULAR GLANDS, COMMONLY OCCURS AFTER UPPER MANTLE RADIATION THERAPY. RADIATION SIALITIS ACCUMULATES 67Ga*

8*IN 67Ga STUDIES:
-FAINT SALIVARY GLAND UPTAKE MAY BE NORMAL
-SLIGHT AXILLARY UPTAKE MAY BE CAUSED BE 67Ga BEING EXCREATED IN SWEAT*

9*67Ga IS A NON-SPECIFIC TUMOR SEEKER AND HAS VARIABLE UPTAKE IN LUNG TUMORS. IT IS RARELY USEFUL IN THE DIFFERENTIAL DIAGNOSIS OF A LUNG MASS*

10*67Ga UPTAKE IN THE LIVER MAY BE DIFFICULT TO INTERPRET*
*A COLLOID LIVER SCAN SHOULD ALWAYS BE PERFORMED FOLLOWING A 67Ga STUDY, AND THEY SHOULD BE INTERPRTED TOGETHER*

11*67Ga IS A GOOD GUIDE TO THE ACTIVITY OF DISEASE WHEN AVID UPTAKE HAS PREVIOUSLY BEEN DEMONSTRATED IN A TUMOR*
