<s>[INST] My husband has lung cancer stage 4. Has been getting treatments since last May.Just had TET/CT and I have 2 questions...Addomen and Pevis there is a slight wall thickening of the bladder which is incompletely distended.Colonie diverticula are present......Expected physiologic uptake in the brain, myocardium, bowel loops and utinary collecting systems [/INST] HelloWelcome to healthcaremagicIt is sad to know that your husband has stage 4 disease. Slight wall thickness in bladder is a usually a normal finding.It can also occur in urinary infection or malignancy  .If the images look doubtful he will be advised cystoscopy otherwise nothing needs to be done,Colonic diverticulum is a  small bulging sac pushing outward from the colon wall which is usually a incidental finding and it requires no treatment except fibre rich diet.Utakes in brain ,myocardium, bowel loops and urinary collecting systems is normal finding.Regards </s>
