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, and resting, a whole-body PET/CT scan was performed.
The whole-body scan showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; and no significant abnormalities were observed in FDG uptake.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed 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; FDG uptake was normal; the pharyngeal recesses were symmetrical; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and FDG uptake was normal.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland was normal in morphology and size, with uniform density; and FDG uptake was normal.
Small lymph nodes, approximately 0.5 cm in short diameter, were observed bilaterally in the deep cervical spaces, submandibular region, and submental region, with some showing mild FDG metabolism (SUVmax = 2.0).
An enlarged lymph node, approximately 1.0 cm in short diameter, was observed in the left supraclavicular fossa, with increased FDG metabolism (SUVmax = 5.3).
Ground-glass nodules were observed in the apical segment of the right upper lobe, the lateral segment of the middle lobe, and the posterior basal segment of the right lower lobe; the latter was larger, with a CT value of approximately -521 HU and a long diameter of approximately 0.4 cm, and no abnormal FDG metabolism was observed.
Multiple solid nodules, approximately 0.2-0.3 cm in long diameter, were observed in the remaining lungs.
A few linear shadows were observed in the left lower lobe, and FDG uptake was normal in all cases.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Enlarged lymph nodes, approximately 1.2 cm in short diameter, were observed in the right hilum and mediastinum (prevascular space, anterior mediastinal thymic region, and paraesophageal region), with increased FDG metabolism (SUVmax = 5.3).
The cardiac imaging was normal.
The esophagus showed no dilation, thickening, or masses; FDG uptake was not increased.
Both breasts were relatively dense; FDG metabolism was normal.
The liver showed no significant abnormalities in shape or size; the liver margins were smooth; the hepatic fissures were not widened; punctate calcifications were observed in the left inner lobe of the liver; FDG uptake was normal.
The main portal vein showed no significant widening; intrahepatic and extrahepatic bile ducts were not dilated.
The pancreas was normal in shape; no significant abnormal density shadows were seen in the parenchyma; the main pancreatic duct was not widened; FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size; no significant abnormal density shadows were seen in the parenchyma; the renal pelvis, calyces, and ureters were not widened; FDG uptake was normal.
Bilateral adrenal gland imaging showed no significant abnormalities.
The stomach was poorly distended; the gastric wall showed no significant thickening; FDG uptake was normal.
The intestines were poorly filled, with no obvious thickening or mass in the intestinal wall, and FDG uptake was normal.
Cystic-solid soft tissue masses were seen in both adnexal regions, the left one being larger, a mass measuring approximately 8.3 6.0 9.0 cm, with irregular margins.
The solid component showed increased FDG metabolism (SUVmax = 10.7), and the tumors were poorly demarcated from the adjacent uterus.
Increased density was observed in the mesentery and greater omentum in the abdominopelvic cavity, with mild FDG uptake (SUVmax = 1.5).
A small amount of fluid-density shadows were seen in the pelvic cavity.
The uterus was full in shape with irregular margins and nodular protrusions; FDG uptake was not abnormally increased.
The bladder was generally full, with no obvious positive stones.
Multiple enlarged lymph nodes were seen in the bilateral pelvic walls, bilateral groins, bilateral diaphragmatic crura, right anterior diaphragmatic group, and retroperitoneal para-aortic region, the largest with a short diameter of approximately 1.3 cm; FDG metabolism was increased (SUVmax = 6.8).
The spinal alignment was normal, with some vertebral body margins showing osteophyte formation.
FDG uptake was normal.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. Bilateral adnexal cystic-solid lesions with increased FDG metabolism in the solid component, suggestive of ovarian cancer. b. Multiple lymph node metastases in the bilateral pelvic walls, bilateral groins, bilateral diaphragmatic crura, right anterior diaphragmatic group, retroperitoneum, and left supraclavicular fossa. Metastasis to the right hilar and mediastinal lymph nodes is highly probable. c. Increased density in the mesentery and greater omentum of the abdominoperineal cavity with mild FDG uptake, suggesting implantation metastasis is highly probable; further clinical correlation is needed. Small amount of pelvic effusion.

2. a. Ground-glass nodules in the apical segment of the right upper lobe, the lateral segment of the middle lobe, and the posterior basal segment of the lower lobe, suggestive of chronic inflammation or atypical adenomatous hyperplasia; annual HRCT follow-up is recommended. b. Multiple inflammatory nodules in the remaining two lungs. A few old lesions in the left lower lobe.

3. Calcification in the left medial lobe of the liver.

4. Uterine fibroids.

5. Spinal osteophyte formation.

6. No obvious abnormalities were observed on cranial imaging. Reactive hyperplasia of bilateral deep cervical spaces, submandibular and submental 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.
