Whole-body 18F-FDG PET/CT scan in a patient with Renal Cancer taken from the PETWB-REP dataset. The following English report (translated from original Chinese) is taken verbatim from the public dataset and has not been modified or otherwise checked for accuracy (see the end for citation).

Findings

Under fasting conditions, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging was then performed with both arms raised, from the top of the skull to the upper thigh.
The brain morphology and structure were normal, with no abnormal density shadows seen in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no significant abnormalities.
No thickening was observed in the paranasal sinus mucosa, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall, and no abnormalities in FDG uptake were seen.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
Physiological uptake was observed in the bilateral palatine tonsils.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
The thyroid gland is normal in shape and size, but its density is somewhat uneven.
Several low-density nodules are seen in both lobes, with clear borders.
The largest nodule has a long diameter of approximately 0.7 cm.
FDG uptake is normal.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
Multiple ground-glass nodules are seen in both lungs, with relatively clear borders.
The largest nodule is located in the left upper lobe and right middle lobe, with a long diameter of approximately 0.7?.9 cm.
Multiple solid micronodules are also seen in both lungs, with clear borders and a long diameter of approximately 0.2?.5 cm.
FDG uptake is normal in all these cases.
No pleural thickening is seen bilaterally, and there is no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions.
The density of the cardiac chambers is lower than that of the myocardium.
No esophageal dilatation, significant wall thickening, or mass is seen in the esophagus.
FDG uptake is normal.
No significant abnormal density is seen in either breast, and FDG uptake is normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
Two nodular FDG uptake shadows were observed at the junction of the left and right lobes of the liver, with SUVmax=7.8, the larger one having an uptake long diameter of approximately 0.9 cm.
The main portal vein showed no obvious widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape and size, with increased density within the gallbladder, no thickening of the gallbladder wall, and no abnormal FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
The stomach was poorly distended, with slight thickening of part of the stomach wall and mildly increased FDG uptake, SUVmax=2.1.
The intestines were poorly filled, with residual contrast agent present.
Thickening of the lower descending colon near the sigmoid colon was observed, with narrowing of the intestinal lumen, affecting approximately 3.0 cm in length.
FDG uptake was increased (SUVmax = 15.1).
Multiple mesenteric lymph nodes were visible, the largest with a short diameter of approximately 0.9 cm, showing increased FDG uptake (SUVmax = 16.0).
The remaining portion of the intestine showed continuous FDG uptake (SUVmax = 7.2).
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
No widening of the renal pelvis, calyces, or ureters was observed, and FDG uptake was normal.
Bilateral adrenal gland contrast imaging showed no obvious abnormalities.
Post-operatively, the uterus was irregular in shape, with uneven myometrial density, and appeared to contain multiple slightly high-density masses, but FDG uptake was not abnormally increased.
Multiple low-density shadows were present in the cervix with indistinct borders, but FDG uptake was normal.
No abnormal FDG uptake was observed in the bilateral adnexa.
No abnormal thickening of the bladder wall was observed, and no obvious positive stones were seen within the bladder.
A small amount of fluid was found in the pelvic cavity.
The spinal alignment was normal, with mild osteophyte formation at the margins of some vertebral bodies.
FDG uptake in the whole body was normal.

Impression

  1. a. Thickening of the lower descending colon near the sigmoid colon with increased FDG metabolism, consistent with colon cancer. Mesenteric lymph node metastasis. Liver metastasis. b. Increased FDG metabolism in the remaining intestinal segment, suggesting physiological changes or inflammatory lesions; chronic gastritis. Please follow up with endoscopy for the above.

  2. Multiple ground-glass nodules in both lungs, normal FDG metabolism, atypical adenomatous hyperplasia or early-stage lung cancer (larger ones) are the primary considerations; CT scan follow-up in 3 months is recommended. Chronic inflammatory micronodules (solid) in both lungs. Anemia.

  3. Nodular goiter, please follow up with ultrasound.

  4. Contrast agent residue or cholestasis in the gallbladder. Contrast agent residue in the intestines.

  5. Multiple uterine fibroids, Nabothian cysts in the cervix, please follow up with ultrasound. Small amount of pelvic effusion.

  6. Mild osteophyte formation in the spine.

  7. No significant abnormalities in FDG metabolism in the brain.

This case is from PETWB-REP, a curated dataset of whole-body 18F-FDG PET/CT scans and corresponding radiology reports from 490 patients with a broad spectrum of malignancies. The data were retrospectively collected from patients who underwent clinically indicated whole-body 18F-FDG PET/CT scans at the Shanghai Universal Medical Imaging Diagnostic Center between 2021 and 2024.
