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 images showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities were observed in FDG uptake.
Slight widening of the ventricles, sulci, fissures, and cisterns was observed; the ventricles were symmetrical bilaterally, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
Mucosal thickening was observed in the bilateral maxillary sinuses, but no increased FDG uptake was observed.
The mucosa of the remaining paranasal sinuses was not thickened, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; no abnormal FDG uptake was observed.
The bilateral pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear, and no abnormal FDG uptake was observed.
The bilateral palatine tonsils showed physiological uptake.
The laryngopharynx was normal in morphology and structure.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in morphology and size, with uniform density; no abnormal FDG uptake was observed.
Several small lymph nodes, approximately 0.6 cm in short diameter, were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
FDG metabolism was normal.
A mass-like soft tissue lesion was observed in the left upper lobe near the hilum, with increased FDG uptake (SUVmax = 13.7).
The left proper upper lobe bronchus was involved and truncated, with a large area of consolidation in the distal anterior segment of the left upper lobe.
Two small nodular shadows, approximately 0.2-0.3 cm in diameter, were observed in the apical and posterior segments of the right upper lobe, with no significant increase in FDG uptake.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Multiple lymph nodes were observed in the left hilum, pretracheal space, para-aortic arch, aortopulmonary window, and subcarinal region, the largest with a short diameter of approximately 1.1 cm.
FDG metabolism was increased (SUVmax = 3.6).
The cardiac silhouette was normal.
Calcification of some arterial walls (including coronary arteries) was 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 thickened walls and no abnormal local FDG uptake.
The pancreas was normal in shape, with no abnormal density shadows in the parenchyma; the main pancreatic duct was not widened, and FDG uptake was normal.
The spleen was normal in shape, size, density, and FDG uptake.
Both kidneys were normal in shape and size; a small cystic density shadow (approximately 7 mm in long diameter) was seen in the right kidney; no other abnormal density shadows were seen in the parenchyma; the renal pelvis, calyces, and ureter were not widened, and FDG uptake was normal.
Both adrenal glands showed increased contrast and FDG uptake, with SUVmax = 3.2.
Slight thickening of the cardia, part of the gastric body, and antrum walls, with mildly increased FDG uptake (SUVmax = 4.0).
Intestinal distension was poor, with no obvious thickening or mass in the intestinal wall; FDG uptake was physiological.
The prostate was enlarged, with a maximum transverse diameter of approximately 6.2 cm, exhibiting heterogeneous density and multiple punctate dense shadows; FDG uptake was not abnormally increased.
The bladder was generally full, with no obvious positive stones.
Several lymph nodes were observed in the bilateral inguinal regions, the largest being approximately 0.8 cm in diameter; some showed mildly increased FDG uptake (SUVmax = 1.9).
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneum; FDG metabolism was normal.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulging; FDG uptake was normal.
Schmorl's nodes were observed in the L5 vertebral body.
A gas density shadow was observed in the L5-S1 intervertebral space.
No abnormal FDG metabolism was observed in the entire skeleton.

Impression

1. a. Soft tissue mass near the hilum of the left upper lobe, with increased FDG uptake, suggesting a high probability of central lung cancer with distal atelectasis; bronchoscopy is recommended. b. Increased FDG metabolism in the left hilar and mediastinal lymph nodes, suggesting possible reactive proliferative lymph nodes, with partial metastasis not ruled out.

2. Inflammatory nodules in the apical and posterior segments of the right upper lobe. Calcification of some arterial walls (including coronary arteries).

3. Chronic cholecystitis. Chronic gastritis is possible; gastroscopy is recommended.

4. Bilateral adrenal hyperplasia is possible; follow-up examination is recommended. Right renal cyst. Benign prostatic hyperplasia with multiple calcifications. Reactive hyperplasia of bilateral inguinal lymph nodes.

5. Degenerative changes in the spine. Schmorl's node in the L5 vertebral body. L5-S1 intervertebral disc degeneration.

6. Mild senile encephalopathy. Bilateral chronic maxillary sinusitis.

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.
