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 normal.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical and showed no obvious abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and FDG uptake was normal.
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, with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
The laryngopharynx was normal in morphology and structure.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with slightly uneven density, and FDG uptake was normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
A soft tissue mass measuring approximately 6.4*3.6cm was observed in the right upper lobe (anterior and apical segments) near the mediastinum, with increased FDG metabolism (SUVmax = 8.5), and distal wedge-shaped consolidation with atelectasis.
Multiple small solid nodules were observed in both lungs, with clear borders, a long diameter of approximately 0.2-0.8cm, some showing mild FDG uptake (SUVmax = 1.2).
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
Multiple lymph nodes were observed in the right hilum and pretracheal space, the largest approximately 1.0cm in short diameter, with increased FDG metabolism (SUVmax = 4.1).
Some arterial walls showed calcification.
The cardiac silhouette appeared normal.
The esophagus showed no dilation, no significant thickening or mass in the esophagus wall, and no increased FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed punctate dense shadows in the right lobe of the liver, with no abnormal FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
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.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormal FDG uptake.
Bilateral adrenal glands showed no obvious abnormalities on contrast.
The stomach was poorly distended, with no significant thickening of the stomach wall and no obvious abnormal FDG uptake.
The intestines were poorly distended, with no obvious thickening or mass in the intestinal wall, and FDG uptake was physiological.
The prostate was normal in size and density, with no abnormally increased FDG uptake.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region.
No obvious fluid accumulation was observed in the abdomen or pelvic cavity.
The spinal alignment was normal, with some vertebral body margin osteophytes.
No abnormal FDG metabolism was observed in the entire skeleton.
FDG metabolism was increased around the right shoulder joint, with SUVmax=3.6.

Impression

1. a. Space-occupying lesion in the upper lobe of the right lung, with increased FDG metabolism, consistent with lung cancer with obstructive atelectasis. b. Bilateral lung metastases are highly probable; regular CT scans are recommended. c. Right hilar and pretracheal lymph node metastases are highly probable. d. A few ischemic lesions in the deep bilateral brain regions; MRI scans are recommended.

2. Partial arterial wall calcification.

3. Bile duct stones or calcifications in the right lobe of the liver; ultrasound follow-up is recommended.

4. Partial vertebral osteophyte formation. Right-sided frozen shoulder.

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.
