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:Patchy low-density shadows in the deep bilateral brain regions, with no significant abnormalities in FDG uptake.
Enlargement of the ventricles, sulci, fissures, and cisterns; symmetrical bilateral ventricles with no midline shift.
Symmetrical bilateral eyeballs with no significant abnormalities.
Thickening of the left ethmoid sinus mucosa, with an intact sinus wall.
No thickening of the nasopharyngeal wall, with no abnormalities in FDG uptake; symmetrical bilateral pharyngeal recesses; no stenosis of the Eustachian tube openings; normal structures of the infratemporal and pterygopalatine fossae; clear bilateral parapharyngeal spaces with no abnormalities in FDG uptake.
Bilateral palatine tonsils showed physiological uptake.
A soft tissue nodule measuring approximately 2.1 1.2 cm was found in the right parotid gland, with increased FDG metabolism (SUVmax = 11.3).
No abnormalities were observed in the morphology and structure of the laryngopharynx.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
An irregular mass measuring approximately 3.52.33.0cm was seen in the right middle lobe of the lung, with lobulated and spiculated margins; FDG metabolism was increased, SUVmax=11.9, and part of it was adhered to the pleura.
Several solid nodules, approximately 0.2-0.5cm in long diameter, with clear borders, were seen in both lungs; FDG metabolism was normal.
Multiple scattered patchy opacities and linear lesions were also seen in both lungs; FDG metabolism was normal.
No pleural thickening was seen bilaterally; there was no pleural effusion or pneumothorax bilaterally.
Several small lymph nodes were seen in the bilateral hilar and mediastinal regions; FDG metabolism was normal.
The cardiac silhouette was normal.
Some arterial walls showed calcification (including the coronary arteries).
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
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; the main pancreatic duct was not widened, and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
A cystic lesion was seen in the right kidney, approximately 1.0 cm in length, with absent FDG uptake.
A slightly high-density nodule, approximately 0.5 cm in length, was also seen at the upper pole of the right kidney; FDG uptake was normal.
The left kidney is normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
There is no widening of the renal pelvis, calyces, or ureter, and no obvious abnormalities in FDG uptake.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is poorly distended, with no obvious thickening of the stomach wall, and no obvious abnormalities in FDG uptake.
The intestines are poorly distended, with increased FDG metabolism in some intestinal segments (SUVmax = 4.5).
The prostate is normal in shape and size, with calcifications in the parenchyma, and no abnormal FDG metabolism.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneal region.
No obvious effusion is seen in the abdominal or pelvic cavities.
A soft tissue mass with indistinct borders is seen in the right back muscles, with localized bone destruction adjacent to the right scapula.
FDG metabolism is increased (SUVmax = 9.2), and the uptake area is approximately 3.3*2.4cm.
The spinal alignment is normal, but the T12 and L1 vertebral bodies are flattened.
Some vertebral bodies show marginal osteophyte formation.
Schmorl's nodes are observed in some thoracic vertebrae.
Mild disc bulging is present at L4/5 and L5/S1, and pneumothorax is present in some thoracic and lumbar vertebrae.

Impression

1. a. A mass in the right middle lobe of the lung with increased FDG metabolism, suggestive of peripheral lung cancer; please correlate with clinical and pathological findings. A soft tissue mass in the right back muscles with bone destruction of the adjacent scapula suggests a high probability of metastasis. b. Multiple solid nodules in both lungs with normal FDG metabolism, suggestive of chronic inflammatory nodules; follow-up CT is recommended. Scattered chronic inflammation and sequelae in both lungs. High probability of reactive hyperplasia of the hilar and mediastinal lymph nodes. Calcification of some arterial walls (including coronary arteries).

2. A soft tissue nodule in the right parotid gland with increased FDG metabolism, suggestive of adenolymphoma or mixed tumor; ultrasound follow-up is recommended.

3. A few ischemic lesions in the deep bilateral brain; senile cerebral hemorrhage; please correlate with MRI for follow-up. Inflammation of the left ethmoid sinus.

4. Right renal cyst, complex cyst. Prostatic calcification.

5. Increased FDG metabolism in some intestinal segments, possibly due to inflammatory or physiological uptake; colonoscopy is recommended.

6. Degenerative changes in the spine. Wedge-shaped changes in the T12 and L1 vertebral bodies. Schmorl's nodes in some thoracic vertebrae. Mild bulging of the L4/5 and L5/S1 intervertebral discs; pneumoconiosis and degeneration in some thoracic and lumbar vertebrae.

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.
