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: Normal brain morphology and structure, with a few patchy low-density shadows in the deep brain regions; no significant abnormalities were observed 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 and showed 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; no abnormalities were observed in FDG uptake; the pharyngeal recesses were symmetrical; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and no abnormalities were observed in FDG uptake.
The 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 slightly uneven density; no abnormalities were observed in FDG uptake.
Several small lymph nodes were observed in the bilateral deep cervical spaces; no abnormalities in FDG metabolism were observed.
Patchy soft tissue shadows were observed in the left lower hilum, with localized bronchial stenosis but still patency, measuring approximately 2.8*2.2cm.
FDG metabolism was slightly elevated, with SUVmax=2.5.
Bronchiectasis was observed in the left lower lobe, with patchy and linear shadows seen distally.
Punctate calcifications were observed in the anterior segment of the right upper lobe.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Several enlarged lymph nodes were observed in the left hilum and below the carina, the largest with a short diameter of approximately 1.1cm, showing elevated FDG metabolism, with SUVmax=9.3.
Multiple small lymph node shadows were observed in the anterior superior mediastinum, between the great vessels, and beside the trachea at the thoracic inlet, the largest with a short diameter of approximately 0.4cm.
Some had higher density and contained calcifications, showing slightly elevated FDG uptake, with SUVmax=3.1.
The cardiac silhouette was normal.
No esophageal dilation was observed, and no significant thickening or mass was seen in the esophageal wall; FDG uptake was not increased.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissures.
A slightly low-density, roundish lesion, approximately 0.9 cm in long diameter, was observed near the diaphragm in the right lobe of the liver on plain CT scan; no abnormal FDG uptake was observed.
No other obvious abnormal density shadows were observed in the liver parenchyma, and 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 and size, and the gallbladder wall showed no thickening; local FDG uptake was normal.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma; the main pancreatic duct was not widened, and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma; the renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
Both adrenal glands were slightly enlarged, with a slightly increased FDG metabolism (SUVmax = 3.2).
The stomach was poorly filled, but the stomach wall was not significantly thickened, and FDG uptake was not significantly abnormal.
The intestines were poorly filled, 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.
No significant fluid accumulation was seen in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes, and L3/4, L4/5, and L5/S1 intervertebral disc bulges.
Pneumothorax was present in the L5/S1 intervertebral disc.
No abnormal FDG metabolism was observed in the entire skeletal system.

Impression

1. Comparison of PET/CT scan of left lung cancer after chemotherapy with the scan taken on December 17, 2021 at our center: a. Soft tissue patchy lesions in the left lower hilum: The lesions have significantly shrunk compared to the previous scan, and the FDG metabolic value has significantly decreased compared to the previous scan, suggesting post-treatment changes and suppression of tumor activity. Bronchiectasis in the left lower lobe, with a small amount of distal inflammation. b. Lymph nodes in the left hilum and below the carina: The lesions have shrunk in size compared to the previous scan, and the FDG metabolic value has increased, suggesting partial suppression of tumor activity. c. Lymph nodes in the anterior superior mediastinum, the space between the great vessels, and the right lateral tracheal inlet: Some have higher density and calcification, with slightly increased FDG uptake, suggesting possible post-treatment changes (partial suppression) of metastatic lymph nodes. Please correlate with clinical findings. d. Slightly low-density shadow near the diaphragm in the right lobe of the liver: This is a newly added lesion compared to the previous scan. No abnormal FDG uptake was observed, suggesting possible artifact. Space-occupying lesions need to be ruled out. Further MRI examination is recommended.

2. Calcification lesions in the anterior segment of the right upper lobe.

3. Bilateral reactive adrenal hyperplasia, please follow up.

4. Partial vertebral osteophyte formation. L3/4, L4/5, and L5/S1 intervertebral disc bulge. L5/S1 intervertebral disc pneumothorax. No abnormal FDG metabolism observed in the entire skeletal system.

5. A few ischemic foci deep within the brain. Bilateral deep cervical lymph node reactive hyperplasia.

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.
