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: The brain morphology and structure were normal.
A cystic low-density lesion, approximately 3.1*1.4cm in cross-section, was seen in the subcranial region of the right frontal lobe, with absent FDG uptake.
No abnormal density shadows were seen in the brain parenchyma, and FDG uptake was not significantly abnormal.
No widening was seen in the ventricles, sulci, fissures, or cisterns.
The ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no obvious abnormalities.
No thickening was seen in the paranasal sinus mucosa, and the sinus walls were intact.
No thickening was seen in the nasopharyngeal wall, and FDG uptake was not abnormal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the parapharyngeal spaces were clear with no abnormal FDG uptake.
Both palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx are normal.
The thyroid gland is normal in shape and size; a low-density nodule approximately 1.1 cm in diameter is seen in the right lobe, with increased FDG metabolism (SUVmax = 6.7).
Multiple low-density and high-density shadows are present in both lobes of the thyroid gland; a punctate calcification is seen in the right lobe, with no abnormal FDG uptake.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
A solid mass is seen in the posterior segment of the right lower lobe, surrounded by ground-glass opacities, with spiculated and lobulated margins, measuring approximately 3.0*2.4 cm, with increased FDG metabolism (SUVmax = 10.8).
A small solid nodule with clear borders is seen in the right middle lobe, approximately 0.6 cm in long diameter, with slightly increased FDG metabolism (SUVmax = 1.3).
Scattered punctate, patchy, and linear shadows are present in the remaining lungs, with no abnormal FDG uptake.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Mediastinal calcifications were present.
Multiple lymph nodes were observed in the bilateral hilar, pretracheal, and aortic windows, the largest with a short diameter of approximately 0.6 cm, showing increased FDG metabolism (SUVmax = 5.1).
Calcification of some arterial walls (including coronary arteries) was present.
The cardiac silhouette appeared normal.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
No significant abnormalities were observed in either breast, and FDG metabolism was normal.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan revealed punctate calcifications within the liver and calcification of the right lobe capsule, 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 appears normal in shape and size, with no thickening of the gallbladder wall and no abnormal FDG uptake in the local area.
The pancreas appears 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 appears normal in shape, size, density, and FDG uptake.
Both kidneys appear normal in shape and size, with scattered low-density lesions in both kidneys with clear borders and absent FDG uptake.
The largest lesion is located in the left kidney, with a long diameter of approximately 2.8 cm.
No widening of the renal pelvis, calyces, or ureters is observed, and no obvious abnormal FDG uptake is seen.
No obvious abnormalities are seen in bilateral adrenal gland imaging.
The stomach is poorly distended, with no obvious thickening of the stomach wall and no obvious abnormal FDG uptake.
The intestines are poorly distended, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
The uterus is normal in shape, with no abnormal density shadows, and no abnormally increased FDG uptake.
No abnormal FDG metabolism is observed in the bilateral adnexa.
The bladder wall is not abnormally thickened, and no obvious positive stones are seen within it.
No enlarged lymph nodes are seen in the abdominopelvic region or retroperitoneal area.
No obvious fluid accumulation is seen in the abdomen or pelvis.
The spinal alignment is normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
Cystic low-density lesions are seen in the sacral canal.
Systemic bone FDG metabolism is normal.

Impression

1. a. A mass in the posterior segment of the right lower lobe with increased FDG metabolism, suggestive of lung cancer. b. A small solid nodule in the right middle lobe with mildly increased FDG metabolism, suggestive of possible metastasis; follow-up with CT scan is recommended. c. Scattered chronic inflammation and sequelae in both lungs. Reactive hyperplasia of hilar and mediastinal lymph nodes. Mediastinal calcification. Calcification of some arterial walls (including coronary arteries).

2. Nodular goiter is highly probable; local malignancy in the right lobe is a possibility, further ultrasound examination is recommended.

3. Punctate calcifications in the liver, calcification of the right lobe capsule. Bilateral renal cysts.

4. Partial vertebral osteophyte formation. L4/5 and L5/S1 intervertebral disc bulges. Sacral canal cysts.

5. Arachnoid cyst in the right frontal region. No obvious abnormalities were found on intracranial FDG imaging.

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.
