Whole-body 18F-FDG PET/CT scan in a patient with Ovarian 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

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed.
The whole-body scan showed: Brain morphology and structure were normal, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; there was no midline shift.
Both eyes were symmetrical, with no obvious abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and FDG uptake was normal.
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.
The base of the tongue and both palatine tonsils were full with increased FDG uptake (SUVmax = 9.2).
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx showed no abnormalities in morphology and structure.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
Bilateral deep cervical spaces and submandibular lymph nodes are visible; the largest has a short diameter of approximately 0.7 cm, with increased FDG uptake (SUVmax = 3.8).
Lung markings are clear bilaterally; multiple solid nodules are present in both lungs, the largest approximately 0.4 cm in diameter, with no abnormal FDG uptake.
A few scattered linear lesions are also present in both lungs, with no abnormal FDG uptake.
No pleural thickening is observed bilaterally; there is no pleural effusion or pneumothorax bilaterally.
Multiple lymph nodes are visible in the bilateral hilar regions, anterior mediastinum, pretracheal space, para-aortic arch, aortopulmonary window, subcarinal region, and left axillary region; the largest has a short diameter of approximately 1.0 cm, with increased FDG uptake (SUVmax = 4.4).
Cardiac silhouette is normal.
The ascending aorta is widened, reaching a maximum width of approximately 4.3 cm, with partial calcification of the arterial wall (including the coronary arteries).
No abnormal density shadows were seen in either breast, and FDG metabolism was normal.
The esophagus was not dilated, and the wall showed no significant thickening or mass; FDG uptake was not increased.
The liver's shape and size were normal, with smooth borders, no widening of the hepatic fissure, and no significant abnormal density shadows in the liver parenchyma on plain CT scan; FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation was seen in the intrahepatic or extrahepatic bile ducts.
The gallbladder's shape and size were normal, the gallbladder wall was not thickened, and local FDG uptake was normal.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened, and FDG uptake was normal.
Spleen morphology, size, density, and FDG uptake were normal.
Both kidneys were normal in shape and size, with a cystic lesion in the left renal parenchyma, approximately 0.8 cm in diameter.
The renal pelvis, calyces, and ureter were not widened, and FDG uptake was not significantly abnormal.
Bilateral adrenal glands showed no significant abnormalities on contrast imaging.
Stomach distension was poor, with slight thickening of the cardia, part of the gastric body, and antrum walls.
FDG uptake was slightly increased, with SUVmax = 2.8.
The peritoneum was extensively thickened and increased in density, presenting as a cake-like or turbid appearance.
Multiple nodules and patches were visible, most notably in the right greater omentum.
FDG uptake was increased, with SUVmax = 5.3.
Abdominal and pelvic effusion was present, with some areas poorly demarcated from adjacent intestinal segments.
The intestinal lumen contained considerable gas and residual contents, but details were poorly visualized.
Lymph nodes in the right anterior diaphragmatic group and right cardiophrenic angle were observed, the largest measuring approximately 0.5 cm in short diameter, with increased FDG uptake (SUVmax = 3.6).
An irregular mass in the right adnexal region, with indistinct borders and uneven density, measuring approximately 3.8 x 2.3 cm, showed increased FDG uptake in the solid portion (SUVmax = 3.9).
The uterus had irregular margins with visible soft tissue density bulges, the largest measuring approximately 4.0 cm in long diameter, with normal FDG uptake.
The bladder was poorly filled, with no obvious positive stones.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. Extensive peritoneal thickening and increased density with nodules and patchy shadows, elevated FDG metabolism, implantation metastasis is the primary consideration; please correlate with clinicopathology. Abdominal and pelvic effusion. b. Right adnexal region mass with elevated FDG metabolism, considered malignant tumor, primary tumor is the primary consideration, metastasis to be ruled out; enhanced MRI is recommended for further examination.

2. Chronic inflammatory micronodules in both lungs. A few post-inflammatory lesions in both lungs. Reactive hyperplasia of hilar, mediastinal, and left axillary lymph nodes.

3. Widening of the ascending aorta, with partial calcification of the arterial wall (including coronary arteries).

4. Left renal cyst. Uterine fibroid to be ruled out. Reactive hyperplasia of right anterior diaphragmatic and right cardiophrenic angle lymph nodes.

5. Partial chronic inflammatory changes in the gastric wall.

6. Degenerative changes in the spine, L4/5 and L5/S1 intervertebral disc bulges.

7. Age-related brain abnormalities, deep lacunar infarcts.

8. Inflammation of the base of the tongue and bilateral palatine tonsils.

9. Reactive hyperplasia of bilateral cervical lymph nodes.

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.
