Whole-body 18F-FDG PET/CT scan in a patient with Lung 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: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; 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; no abnormalities were observed in FDG uptake; 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 no abnormalities were observed in FDG uptake.
The palatine tonsils showed physiological uptake.
The laryngopharynx was normal in morphology and structure.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in morphology and size, with uniform density; no abnormalities were observed in FDG uptake.
No enlarged lymph nodes were observed bilaterally in the neck; no abnormalities in FDG metabolism were observed.
An irregular nodule measuring approximately 1.8 1.5 cm was observed in the anterior segment of the right upper lobe, with lobulated margins and increased FDG metabolism (SUVmax = 10.9).
A small ground-glass nodule with a CT value of approximately -596 HU and a long diameter of approximately 0.4 cm was observed in the apical segment of the right upper lobe, with relatively clear borders and normal FDG metabolism.
Another solid nodule with a long diameter of approximately 0.4 cm and clear borders was observed in the apical segment of the right upper lobe, with normal FDG metabolism.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were observed bilaterally in the hilum and mediastinum.
The cardiac silhouette was normal.
The esophagus was not dilated, and the esophageal wall was not significantly thickened or swollen; FDG uptake was not increased.
Both breasts were normal, and FDG metabolism was normal.
The liver was normal in shape and size, with smooth borders, no widening of the hepatic fissure, and no significant abnormal density shadows were observed in the liver parenchyma on plain CT scan; FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder appeared normal in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
A cystic lesion, approximately 1.2 cm in long diameter, with clear borders, was observed in the head of the pancreas.
FDG uptake was absent.
No significant abnormal density shadows were observed in the remaining pancreatic parenchyma.
The main pancreatic duct was not widened, and FDG uptake was not significantly abnormal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no significant abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was not significantly abnormal.
Bilateral adrenal glands showed no significant abnormalities on contrast.
The stomach was poorly distended, with no significant thickening of the stomach wall and no significant abnormality in FDG uptake.
The intestines were poorly distended, with increased FDG metabolism in some intestinal segments (SUVmax = 4.5).
The uterus was full in shape, with uneven density and unevenly increased FDG metabolism (SUVmax = 3.4).
Cystic lesions were observed in both adnexal regions, the largest being approximately 2.5 cm in long diameter, with increased FDG metabolism at the periphery (SUVmax = 3.2).
The bladder was generally full, with no obvious positive stones.
Several lymph nodes were observed adjacent to the left iliac vessels and in both pelvic walls, the largest being located adjacent to the left iliac vessels, approximately 1.0 cm in short diameter, with increased FDG metabolism (SUVmax = 3.2).
A small amount of pelvic effusion was present.
The spinal alignment was normal, and the bone structure of each vertebra was intact.
No abnormal FDG metabolism was observed in the entire skeleton.

Impression

1. a. Irregular nodule in the anterior segment of the right upper lobe, with increased FDG metabolism, strongly suggestive of lung cancer; further clinical and pathological examination is recommended. b. Ground-glass nodule in the apical segment of the right upper lobe, with normal FDG metabolism, suggestive of inflammatory nodule or atypical adenomatous hyperplasia; annual HRCT follow-up is recommended. Chronic inflammatory nodule in the apical segment of the right upper lobe.

2. Cystic mass in the head of the pancreas, with absent FDG uptake, suggestive of a cyst; neoplastic lesion to be ruled out; further enhanced MRI is recommended.

3. Increased FDG metabolism in some intestinal segments, suggestive of inflammatory or physiological uptake.

4. Full-shaped uterus with uneven density and unevenly increased FDG metabolism, strongly suggestive of adenomyosis; bilateral adnexal ovarian physiological cysts are also highly likely. Ultrasound follow-up is recommended for all of the above. Reactive hyperplasia of lymph nodes adjacent to the left iliac vessels and bilateral pelvic walls. Small amount of pelvic effusion.

5. No abnormalities found on cranial scintigraphy.

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.
