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 scan showed: a few punctate low-density shadows in the deep bilateral cerebral regions; no abnormal density shadows were observed in the remaining brain parenchyma, and FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical bilateral ventricles and no midline shift.
Both eyeballs were symmetrical and showed no obvious abnormalities.
The left maxillary sinus mucosa was thickened, but the sinus wall was intact.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
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.
Both palatine tonsils showed physiological uptake.
The laryngopharynx was normal in morphology and structure.
Several soft tissue nodules were observed in both parotid glands, the largest being on the left side, measuring approximately 1.5 1.2 cm, with increased FDG metabolism (SUVmax = 9.2).
No abnormal density shadows were observed in the bilateral submandibular glands.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
No enlarged lymph nodes are seen bilaterally in the neck, and FDG metabolism is normal.
An irregular mass measuring approximately 4.0 3.9 cm is seen near the hilum of the right upper lobe, with increased FDG metabolism (SUVmax = 15.2).
Several punctate and patchy density shadows are seen around the mass, with normal FDG metabolism.
Stenosis and occlusion of the right upper lobe bronchus are observed.
Multiple scattered patchy and punctate hazy shadows are seen in the remaining lungs, with normal FDG metabolism.
No pleural thickening is seen bilaterally, and there is no pleural effusion or pneumothorax bilaterally.
Multiple enlarged lymph nodes are seen in the bilateral hilum, pretracheal space, para-aortic arch, aortopulmonary window, and below the carina, the largest being located in the right hilum, with a short diameter of approximately 1.2 cm, and increased FDG metabolism (SUVmax = 13.3).
The cardiac silhouette is normal.
Calcification of some arterial walls (including coronary arteries) is observed.
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.
The spleen was normal in shape, size, density, and FDG uptake.
A cystic lesion was observed in the left kidney, approximately 0.8 cm in long diameter, with absent FDG uptake.
The right kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureter, and no obvious abnormal FDG uptake.
Bilateral adrenal gland imaging showed no obvious abnormalities.
The stomach is not fully full, with slight thickening of the walls in parts of the gastric body and antrum.
FDG uptake is slightly increased, SUVmax = 2.1.
The intestines are not fully full, with increased FDG metabolism in parts of the intestines, SUVmax = 4.5 (considered physiological uptake).
The prostate is of normal size and uniform density, with no abnormally increased FDG uptake.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneal region, and FDG metabolism is normal.
No significant fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes, and some calcification of the anterior longitudinal ligament, nuchal ligament, and supraspinous ligament.
L4/5 and L5/S1 intervertebral disc bulges, with no abnormal FDG uptake.
FDG uptake is increased in the right shoulder area, SUVmax = 2.9.

Impression

1. a. A mass near the hilum in the right upper lobe of the lung, with increased FDG metabolism, suggestive of central lung cancer with obstructive inflammation or airway dissemination. Right hilar lymph node metastasis. Reactive hyperplasia of the left hilar and mediastinal lymph nodes is highly probable; follow-up is recommended. b. Scattered inflammation in the remaining lungs. Calcification of some arterial walls (including coronary arteries).

2. Left renal cyst.

3. Slight thickening of the walls of part of the gastric body and antrum, with mildly increased FDG uptake, suggestive of chronic gastritis; follow-up with gastroscopy is recommended.

4. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge. Right shoulder periarthritis.

5. Multiple nodules in both parotid glands, with increased FDG metabolism, suggestive of adenolymphoma; follow-up with MRI is recommended.

6. A few ischemic lesions in the deep bilateral brain regions, suggestive of senile encephalopathy. Chronic inflammation of the left 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.
