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, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging revealed: A few punctate low-density shadows were observed in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma.
FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were widened.
The ventricles were symmetrical, with no midline shift.
The eyeballs were symmetrical, with no obvious abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, 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.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx showed no abnormalities in morphology or structure.
The thyroid gland is normal in shape, with uniform density in both lobes.
FDG metabolism is increased, SUVmax=3.5.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
A large area of consolidation was observed in the left upper lobe, with a higher density mass near the hilum.
FDG metabolism was increased, SUVmax=9.4, with an uptake range of approximately 3.13.4cm.
Several small solid nodules were observed in both lungs, with a long diameter of approximately 0.2-0.4cm and clear borders.
FDG metabolism was normal.
Scattered punctate and linear lesions were also observed in both lungs.
FDG metabolism was normal.
The pleura was slightly thickened bilaterally, but there was no pleural effusion or pneumothorax bilaterally.
Multiple enlarged lymph nodes were observed in the bilateral hilar regions, superior mediastinal vascular space, pretracheal space, para-aortic arch, aortic window, subcarinal region, and parabronchial region of the right lower lobe basal segment.
The largest lymph node had a short diameter of approximately 1.5 cm, with increased FDG metabolism (SUVmax = 8.9).
The cardiac silhouette was normal.
Calcification was observed in some arterial walls (including the coronary arteries).
Slight thickening of the esophageal wall was observed in the lower segment near the cardia, with increased FDG metabolism (SUVmax = 3.6).
Both breasts were normal, with no abnormalities in FDG metabolism.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Multiple cystic lesions were observed within the liver, the largest with a long diameter of approximately 1.8 cm, showing absent FDG uptake.
The main portal vein was not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
Gallbladder: No abnormalities in shape or size.
Gallbladder wall slightly thickened.
Several punctate dense shadows are seen in the neck.
FDG uptake is normal.
Pancreas: Normal shape.
No obvious abnormal density shadows are seen in the parenchyma.
The main pancreatic duct is not widened.
FDG uptake is normal.
Spleen: No abnormalities in shape, size, density, or FDG uptake.
Kidneys: Normal shape and size.
No obvious abnormal density shadows are seen in the parenchyma.
The renal pelvis, calyces, and ureters are not widened.
FDG uptake is normal.
Bilateral adrenal glands are slightly thickened.
FDG metabolism is increased.
SUVmax = 3.4.
Stomach: Poor distension.
Stomach wall is not significantly thickened.
FDG uptake is normal.
Intestinal distension: Poor distension.
Slight thickening of the ascending colon wall in some areas.
FDG metabolism is increased.
SUVmax = 5.9.
Uterine atrophy, no abnormal FDG metabolism observed.
No abnormal FDG metabolism observed in the bilateral adnexa.
Bladder is generally full, no obvious positive stones observed.
Several enlarged lymph nodes are observed around the pancreatic head, the largest with a short diameter of approximately 0.8 cm, showing increased FDG metabolism (SUVmax = 5.9).
No obvious fluid accumulation is observed in the abdomen or pelvis.
The spinal alignment is normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulging.
Systemic bone marrow FDG metabolism is normal.
Increased FDG metabolism is observed around the right shoulder joint (SUVmax = 3.1).
Symmetrical increased FDG metabolism is observed in the bilateral costovertebral joint areas (SUVmax = 5.3).

Impression

1. a. A mass in the left upper lobe of the lung, with increased FDG metabolism, suggestive of lung cancer with obstructive atelectasis. Metastasis to lymph nodes in the bilateral hilar, mediastinal, right lower lobe basal segment, peribronchial, and pancreatic head regions. b. Several small, solid, chronic inflammatory nodules in both lungs. Scattered chronic inflammation and old lesions in both lungs. Slight thickening of the pleura bilaterally. Calcification of some arterial walls (including coronary arteries).

2. Multiple cysts in the liver. Chronic cholecystitis; gallstones in the neck of the gallbladder. Bilateral adrenal hyperplasia is possible; follow-up CT is recommended.

3. Slight thickening of the lower esophageal wall near the cardia, with increased FDG metabolism, suggestive of inflammation; slight thickening of the ascending colon wall with increased FDG metabolism, suggestive of inflammatory or physiological uptake. Please follow up with endoscopy.

4. Uniform density in both lobes of the thyroid gland, increased FDG metabolism, suggestive of nodular goiter; ultrasound and thyroid function follow-up are recommended.

5. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge. Right shoulder periarthritis. Symmetrical increased FDG metabolism in the bilateral costovertebral joint areas, suggestive of brown adipose tissue uptake.

6. A few ischemic lesions in the deep bilateral brain regions, suggestive of age-related brain changes.

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.
