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

Under fasting conditions, 18F-FDG was administered intravenously, and the patient rested before undergoing whole-body PET/CT imaging.
The whole-body imaging showed:Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities were observed in FDG metabolism.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
No abnormalities were observed in the morphology and outline of the bilateral eyeballs; the retrobulbar structures were clear; the optic nerves were symmetrical; and no abnormal FDG metabolism was observed.
No thickening was observed in the paranasal sinus mucosa; the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; there was no stenosis in the bilateral pharyngeal recesses or Eustachian tube openings; the infratemporal fossa and pterygopalatine fossa structures were normal; the bilateral parapharyngeal spaces were clear; and no abnormalities in FDG metabolism were observed.
FDG metabolism in the oropharynx and laryngopharynx was physiological.
No abnormal contrast was observed in the bilateral parotid and submandibular glands.
Sclerotic mastoid process was observed on the left side; the right mastoid air cells were underdeveloped.
The thyroid gland is normal in shape and size, with uniform density, and FDG metabolism is normal.
Bilateral deep cervical spaces and submandibular lymph nodes are visible, the largest being approximately 0.6 cm in short diameter; FDG metabolism is normal.
An irregularly lobulated soft tissue density mass is seen near the oblique fissure in the posterior segment of the right upper lobe, with relatively clear borders, measuring approximately 3.0*2.3*1.5 cm in cross-section; FDG metabolism is increased, SUVmax=6.6.
Two solid nodules are seen in the posterior segment of the right lower lobe and the apical segment of the right upper lobe; the former is larger, approximately 1.5 cm in long diameter, with clear borders; FDG metabolism is increased, SUVmax=4.0.
Several small solid nodules are present in both lungs, with regular shape and clear borders, approximately 0.3-0.4 cm in long diameter; FDG uptake is normal.
A few linear and flocculent density shadows are also seen in both lungs; FDG metabolism is normal.
Slight thickening of the pleura bilaterally, with no pleural effusion or pneumothorax bilaterally.
Right hilar and mediastinal (pretracheal, posterior to the vena cava, subcarinal) lymph nodes are visible; the largest has a short diameter of approximately 1.1 cm, with increased FDG metabolism (SUVmax = 5.9).
Cardiac silhouette is normal.
Liver morphology and size are normal, with smooth borders and no widening of the hepatic fissure.
Plain CT scan shows no obvious abnormal density shadows in the liver parenchyma, and FDG metabolism is normal.
The main portal vein is not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
Gallbladder morphology and size are normal, with no thickening of the gallbladder wall and no local FDG metabolism abnormalities.
Pancreas morphology is normal, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious FDG metabolism abnormalities.
Spleen is absent postoperatively.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
No widening of the renal pelvis, calyces, or ureters is observed, and FDG metabolism is normal.
No obvious abnormalities are seen on bilateral adrenal gland contrast.
The esophagus is not dilated, and no obvious thickening or mass is seen in the esophageal wall; FDG metabolism is not increased.
The stomach is generally full, with no obvious thickening of the stomach wall; FDG metabolism is normal.
The intestines are poorly full, with no obvious thickening or mass in the intestinal wall; FDG metabolism is physiological.
The prostate is enlarged, with a transverse diameter of approximately 5.2 cm; no obvious abnormal density shadows are seen in the parenchyma; FDG metabolism is normal.
The bladder is poorly full, and no obvious positive stones are seen within it.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneal region.
No obvious effusion is seen in the abdominal or pelvic cavities.
Bilateral inguinal lymph nodes were observed, the largest with a short diameter of approximately 1.0 cm; FDG metabolism showed no significant abnormalities.
The spinal alignment was normal, with some vertebral body margin osteophytes.
L4/5 and L5/S1 intervertebral disc bulges were observed; FDG metabolism was normal.
The right 5th/6th rib cortex showed irregular morphology with localized dense shadows; FDG metabolism was normal.

Impression

1. a. A mass in the posterior segment of the right upper lobe, with increased FDG metabolism, consistent with lung cancer, and metastasis to the right hilar and part of the mediastinal lymph nodes. b. Metastasis to the posterior segment of the right lower lobe and the apical segment of the right upper lobe; several solid micronodules in the remaining two lungs, without high FDG metabolism; please follow up with CT scan. A few post-inflammatory lesions in both lungs. Mild pleural thickening bilaterally.

2. Spleen absent post-surgery. Benign prostatic hyperplasia. Highly likely reactive hyperplasia of the bilateral inguinal lymph nodes; ultrasound follow-up is recommended.

3. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge. Post-fracture changes of the right 5th/6th rib.

4. No obvious abnormalities seen on cranial scintigraphy; MRI is recommended. Left sclerotic mastoid process; right mastoid air cell hypoplasia. Reactive hyperplasia of bilateral deep cervical spaces and submandibular lymph nodes.

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.
