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: A soft tissue nodule approximately 0.8 cm in diameter was visible in the right fronto-occipital lobe, with relatively clear borders, increased FDG metabolism (SUVmax = 6.2), and a large area of low-density edema surrounding it.
Localized increased bone density was observed in the right frontal bone, slightly to the right, measuring approximately 2.1 1.1 cm, with no abnormal FDG metabolism.
Both eyeballs were symmetrical and showed no obvious abnormalities.
A small amount of mucosal thickening was observed in the left maxillary sinus, with an intact sinus wall.
The infratemporal fossa and pterygopalatine fossa were structurally normal, with no abnormal FDG uptake.
Both palatine tonsils showed physiological uptake.
No abnormal density shadows were seen 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 no abnormal FDG uptake.
Several small lymph nodes, approximately 0.8 cm in short diameter, were observed in the bilateral deep cervical spaces, submandibular region, and submental region, with mildly elevated FDG metabolism (SUVmax = 1.6).
A 2.4 3.1 cm soft tissue mass was observed paravertebrally in the posterior segment of the left lower lobe, with irregular borders, lobulation, and spiculation.
The adjacent pleura was thickened and the boundary between the mass and the mass was unclear.
FDG metabolism was elevated (SUVmax = 6.6).
Several faint small nodular shadows with relatively clear borders and a ground-glass appearance were observed in the apical-posterior segment of the left upper lobe and the right middle lobe, with a maximum diameter of approximately 0.6 cm.
FDG uptake was normal.
Small nodules, approximately 0.6 cm in maximum diameter, were observed in the lateral basal segment and oblique fissure of the right lower lobe, with normal FDG metabolism.
A punctate calcification was observed in the posterior segment of the right lower lobe.
Scattered linear shadows were observed at the bases of both lungs.
There was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
The esophagus showed no dilation, thickening or masses in the esophageal wall, and no increased FDG uptake.
Both breasts were relatively dense, and FDG metabolism was normal.
The liver showed no significant abnormalities in shape or size, with smooth borders, no widening of the hepatic fissure, and no abnormal density shadows 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 showed no abnormalities in shape or size, no thickening of the gallbladder wall, and no abnormal local FDG uptake.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormal FDG uptake.
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, no widening of the renal pelvis, calyces, or ureters, and no significant abnormal FDG uptake.
Bilateral adrenal glands showed no significant abnormalities on contrast.
The stomach was poorly distended, with no significant thickening of the gastric wall and no significant abnormal FDG uptake.
Increased continuous FDG metabolism in the ascending colon, transverse colon, descending colon, sigmoid colon, and rectum (SUVmax = 5.4).
The uterus is normal in shape, with no abnormal density shadows, and no abnormally increased FDG uptake.
No abnormal FDG metabolism was observed in the bilateral adnexa.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region, and FDG metabolism was normal.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes, L4/5 intervertebral disc bulging, and bone destruction in the left sacral region (S2 level), showing increased FDG metabolism (SUVmax = 6.8).
Increased FDG metabolism was observed in the right shoulder joint capsule (SUVmax = 3.1).

Impression

1. a. Space-occupying lesion in the posterior segment of the left lower lobe, with increased FDG metabolism, suggestive of lung cancer. b. Metastatic tumor in the right frontoparietal lobe. Metastatic tumor in the left sacral region (S2).

2. a. Ground-glass nodules in the apical-posterior segment of the left upper lobe and the right middle lobe, with normal FDG metabolism, suggestive of atypical adenomatous hyperplasia; annual HRCT follow-up is recommended. b. Chronic inflammatory nodules in the lateral basal segment and para-oblique fissure of the right lower lobe, calcification in the right lower lobe, and a few fibrotic lesions at the bases of both lungs.

3. Reactive hyperplasia of bilateral deep cervical spaces, submandibular, and submental lymph nodes.

4. Continuous increased FDG metabolism in the colon and rectum, suggestive of inflammation or physiological uptake; colonoscopy follow-up is recommended.

5. Spinal osteophyte formation, L4/5 intervertebral disc bulge. Increased FDG metabolism in the right shoulder joint capsule, suggestive of frozen shoulder. Benign bone disease of the right frontal bone is highly probable.

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.
