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 few punctate low-density shadows in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma, and FDG uptake was not significantly abnormal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the bilateral ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical and showed no obvious abnormalities.
No thickening was observed in the paranasal sinus mucosa, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall, and FDG uptake was not abnormal.
The bilateral 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, with no abnormal FDG uptake.
Increased FDG metabolism was observed in both palatine tonsils, with SUVmax = 6.9.
No abnormalities were observed in the morphology and structure of the laryngopharynx.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with uniform density, and FDG uptake was not abnormal.
A stenotic obstruction of the bronchus in the posterior segment of the right lower lobe, accompanied by an irregular mass measuring approximately 5.4 4.8 2.5 cm, shows elevated FDG metabolism (SUVmax = 29.7), with surrounding patchy shadows.
The mass also involves the right upper lobe.
Several solid micronodules, approximately 0.2-0.3 cm in long diameter, with clear borders, are seen in the posterior segments of both lower lobes and the right middle lobe, with normal FDG metabolism.
A few linear and patchy lesions are also seen in both lungs, with normal FDG metabolism.
No pleural thickening is observed bilaterally, and there is no pleural effusion or pneumothorax bilaterally.
Multiple enlarged lymph nodes are seen in the right hilum, right upper mediastinum, pretracheal space, aortic window, subcarinal region, right paraesophageal region, and right supraclavicular fossa, the largest with a short diameter of approximately 1.5 cm, showing elevated FDG metabolism (SUVmax = 14.8).
The cardiac silhouette is normal.
The esophagus showed no dilation, thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver was normal in shape and 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 was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
A splenic nodule, approximately 1.0 cm in long diameter, was observed adjacent to the spleen; FDG metabolism was normal.
The spleen was normal in shape, size, density, and FDG uptake.
Both kidneys were normal in shape and size; a small nodular dense shadow was observed in the left kidney; the renal pelvis, calyces, and ureter were not widened; FDG uptake was normal.
Bilateral adrenal glands showed no obvious abnormalities on contrast imaging.
The stomach was not fully full, but the stomach wall was not significantly thickened, and FDG uptake was not significantly abnormal.
The intestines were not fully full, but the intestinal wall was not significantly thickened or lumpy, and FDG uptake was physiological.
The prostate was of normal size and uniform density, and FDG uptake was not abnormally increased.
The bladder was generally full, and no obvious positive stones were seen.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region, and FDG metabolism was not abnormal.
No obvious fluid accumulation was seen in the abdominal or pelvic cavities.
The spinal alignment was normal, with a small amount of osteophyte formation at the edges of some vertebrae, and FDG uptake was not abnormal.
No abnormal FDG metabolism was observed in the entire skeleton.

Impression

1. A mass in the posterior segment of the right lower lobe, with elevated FDG metabolism, consistent with lung cancer with obstructive inflammation, involving the right upper lobe; multiple lymph node metastases in the right hilum, mediastinum, and right supraclavicular fossa.

2. Several small, solid, chronic inflammatory nodules in both lungs. A few chronic inflammatory lesions and old lesions in both lungs.

3. Calcification in the left kidney. Accessory spleen.

4. Mild osteophyte formation in the cervical, thoracic, and lumbar spine.

5. A few ischemic lesions in the deep bilateral brain regions. Chronic inflammation of both palatine tonsils.

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.
