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, and resting, a whole-body PET/CT scan was performed.
The whole-body scan showed: The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, with no significant 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.
Increased FDG metabolism was observed in both palatine tonsils, with SUVmax = 10.4.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
Several small lymph nodes are seen in the bilateral deep cervical spaces, the largest with a short diameter of approximately 0.4 cm; FDG metabolism is slightly increased, SUVmax=3.3.
An irregular soft tissue mass is seen in the right lower lobe, involving the right hilum, with local bronchial obstruction; it measures approximately 6.6*5.0 cm; FDG metabolism is increased, SUVmax=12.2.
Patchy shadows are seen in the right middle lobe; FDG metabolism is increased, SUVmax=7.5.
Multiple solid nodules are present in both lungs, with clear borders, a long diameter of approximately 0.3-0.8 cm; FDG uptake is normal.
Bilateral pleural thickening with multiple calcifications is present.
A slightly enlarged lymph node in the right hilum, with a short diameter of approximately 0.8 cm, shows increased FDG uptake, SUVmax=7.8.
Several small lymph nodes were observed in the mediastinum, the largest with a short diameter of approximately 0.5 cm.
FDG uptake was normal.
The cardiac silhouette was normal.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, no significant thickening or mass in the wall, and no increased FDG uptake.
Both breasts showed no significant abnormalities, and FDG metabolism was normal.
The liver showed no significant abnormalities in shape or size, with smooth borders, no widening of the hepatic fissure, and no significant abnormal density shadows in the liver parenchyma on plain CT scan.
FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, no thickening of the gallbladder wall, and no abnormal local FDG uptake.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormal FDG uptake.
Spleen morphology, size, density, and FDG uptake were normal.
Both kidneys were normal in shape and size.
A low-density lesion with a long diameter of approximately 2.2 cm was seen in the left kidney, with clear borders and absent FDG uptake.
The renal pelvis, calyces, and ureter were not widened, and FDG uptake was not significantly abnormal.
The left adrenal gland was slightly enlarged, but FDG uptake was not abnormal.
The right adrenal gland showed no significant abnormalities on contrast imaging.
Stomach distension was poor, but the stomach wall was not significantly thickened, and FDG uptake was not significantly abnormal.
Intestinal distension was poor, but the intestinal wall was not significantly thickened or showed masses; FDG uptake was physiological.
The uterus was normal in shape, with no abnormal density shadows, and FDG uptake was not abnormally increased.
No abnormal FDG metabolism was seen in the bilateral adnexa.
The bladder was generally full, and no obvious positive stones were seen.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes and L5/S1 intervertebral disc bulging with pneumothorax and posterior calcification.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. Soft tissue mass in the lower lobe of the right lung with increased FDG metabolism, suggestive of lung cancer; bronchoscopy recommended. Obstructive inflammation in the middle lobe of the right lung. b. Multiple solid nodules in both lungs, FDG uptake normal; likely chronic inflammatory nodules; follow-up CT scan recommended to rule out other possible causes. c. Possible right hilar lymph node metastasis. Reactive hyperplasia of mediastinal lymph nodes. Bilateral pleural thickening with multiple calcifications. Calcification of some arterial walls (including coronary arteries).

2. Left renal cyst. Left adrenal hyperplasia.

3. Partial vertebral osteophyte formation. L5/S1 intervertebral disc bulge with pneumothorax and posterior margin calcification.

4. Bilateral palatine tonsillitis. Reactive hyperplasia of bilateral deep cervical lymph nodes.

5. No obvious abnormalities were found on cranial scintigraphy. No obvious space-occupying lesions were found in the sellar region.

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.
