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; FDG uptake showed no significant abnormalities.
The ventricles, sulci, fissures, and cisterns were widened.
The ventricles were symmetrical, with no midline shift.
The eyeballs were symmetrical, with no significant abnormalities.
The right maxillary sinus mucosa was slightly thickened, but the sinus walls were intact.
The nasopharyngeal walls were not thickened; FDG uptake showed no abnormalities.
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; FDG uptake showed no abnormalities.
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 shape and size, with slightly uneven density; FDG uptake showed no abnormalities.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
The left upper lobe near the hilum showed enlargement with soft tissue shadow, fusing with multiple enlarged lymph nodes into a mass approximately 4.1 2.5 cm in cross-section.
FDG metabolism was increased, SUVmax = 21.3, with lobulated margins.
Stenosis and occlusion of the left upper lobe bronchus were observed.
Several miliary nodules, approximately 0.2?.3 cm in long diameter, with clear borders, were observed in the upper lobes of both lungs.
No abnormalities were observed in FDG metabolism.
A few calcifications and linear lesions were also observed in both lungs, with no abnormalities in FDG metabolism.
The cardiac silhouette was normal.
Calcification was observed in some arterial walls.
The esophagus was not dilated, and the esophageal wall was not significantly thickened or lumped.
FDG uptake was not increased.
Gastric distension was poor, and the gastric wall was not significantly thickened.
FDG uptake was not significantly abnormal.
Intestinal distension was poor, with increased FDG metabolism in some intestinal segments (SUVmax = 3.6).
The liver showed no obvious abnormalities in shape or size, with smooth liver margins and no widening of the hepatic fissure.
Plain CT scan showed no obvious abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no obvious widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, with slightly thickened gallbladder walls and round, dense shadows within the lumen; FDG metabolism was normal.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, and no widening of the main pancreatic duct; FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
A splenic nodule was observed adjacent to the spleen, with a long diameter of approximately 0.6 cm; FDG metabolism was normal.
A cystic lesion was seen in the right kidney, approximately 0.8 cm in long diameter, with absent FDG uptake.
The left kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma, and no widening of the renal pelvis, calyces, or ureter.
No obvious abnormalities in FDG uptake were observed.
Both adrenal glands were slightly enlarged.
The prostate was full in shape, approximately 5.1 cm in transverse diameter, with punctate calcifications inside, and increased FDG metabolism (SUVmax = 3.2).
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdomen, pelvis, or retroperitoneal region.
No obvious fluid accumulation was seen in the abdomen or pelvis.
The spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies and L3/4 and L4/5 intervertebral disc bulging.
Flocculent soft tissue shadows were seen subcutaneously in the left buttock, with increased FDG metabolism (SUVmax = 3.2).
No abnormalities were observed in FDG uptake in the bones.

Impression

1. a. Mass near the hilum of the left upper lobe, with increased FDG metabolism, consistent with central lung cancer, and left hilar lymph node metastasis. b. Chronic inflammatory micronodules in the upper lobes of both lungs. A few chronic inflammations and old lesions (including calcifications) in both lungs. Calcification of some arterial walls.

2. Chronic cholecystitis; gallstones. Accessory spleen. Right renal cyst. Mild bilateral adrenal hyperplasia; follow-up is recommended.

3. Increased FDG metabolism in some intestinal segments, considered inflammatory or physiological uptake; colonoscopy is recommended.

4. Benign prostatic hyperplasia with calcification, increased FDG metabolism in the gland, considered inflammatory or physiological uptake; follow-up PSA and ultrasound are recommended.

5. Degenerative changes in the spine. L3/4 and L4/5 intervertebral disc bulge. Subcutaneous inflammation in the left buttock.

6. A few ischemic lesions in the deep bilateral brain regions; age-related brain condition, MRI recommended. Chronic inflammation of the right maxillary sinus.

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.
