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

Under fasting conditions, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging revealed: A few punctate low-density shadows were observed in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma.
FDG uptake was normal.
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 bilaterally, with no obvious abnormalities.
No thickening was observed in the paranasal sinus mucosa; the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear, and FDG uptake was normal.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland is normal in shape and size.
A small, low-density nodule, approximately 0.3 cm in long diameter, is seen in the left lobe, with a minimum CT value of approximately -31 HU.
FDG metabolism is normal.
The right lobe shows uneven density, but FDG uptake is normal.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
An irregular mass, approximately 4.3 3.8 cm in size, is seen in the posterior segment of the right upper lobe, with lobulated and spiculated margins.
FDG metabolism is increased, with SUVmax = 6.7.
Several solid micronodules, approximately 0.2?.4 cm in long diameter, with clear borders, are seen in both lungs.
FDG metabolism is normal.
A few punctate and linear lesions are also seen in both lungs, with FDG metabolism normal.
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 cardiac silhouette is normal.
Some arterial walls show calcification.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
The stomach was poorly filled, but the stomach wall showed no significant thickening, and FDG uptake was normal.
The intestines were poorly filled, but the intestinal wall showed no significant thickening or mass, and FDG uptake was physiological.
The liver showed no significant abnormalities in shape or size, with smooth liver margins, no widening of the hepatic fissures, and decreased heterogeneity in liver density, with the lowest CT value approximately 40 HU.
FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
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 abnormalities in FDG uptake.
Spleen morphology, size, density, and FDG uptake were normal.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
The prostate was normal in shape and size, with uniform density, and no abnormal FDG metabolism was observed.
The bladder was generally full, and no obvious positive stones were observed.
No enlarged lymph nodes were observed in the abdomen, pelvis, or retroperitoneal region.
No obvious effusion was observed in the abdomen or pelvis.
The spinal alignment was normal, with some vertebral body margin osteophytes, L4/5 and L5/S1 intervertebral disc bulging; bilateral L5 spondylolysis was absent, and FDG metabolism was normal.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. A mass in the posterior segment of the right upper lobe, with increased FDG metabolism, suggestive of lung cancer. b. Several solid micronodules of chronic inflammatory origin in both lungs. Minor chronic inflammation and old lesions in both lungs. Partial arteriosclerosis.

2. A low-density nodule in the left lobe of the thyroid gland, with normal FDG metabolism, suggestive of a benign nodule, most likely a lipoma; ultrasound examination recommended.

3. Heterogeneous fatty liver.

4. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges. Bilateral L5 vertebral arch disintegration.

5. A few ischemic lesions in the deep bilateral brain regions; follow-up MRI recommended.

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.
