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: Brain morphology and structure were normal, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; there was no midline shift.
Both eyes 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 and structure.
The thyroid gland is normal in shape and size, but its density is somewhat heterogeneous.
There are low-density nodules in both lobes, the largest being approximately 1.0 cm in long diameter.
FDG uptake is normal.
The lung markings are clear.
Irregular nodules and patchy soft tissue density shadows are present in the right upper lobe and the posterior segment of the adjacent lower lobe near the hilum.
The borders are indistinct, some are fused, and the density is somewhat heterogeneous.
The largest cross-sectional size is approximately 7.3*5.1 cm.
FDG uptake is increased, SUVmax=14.6.
Adjacent bronchi are compressed, and the posterior segment of the upper lobe bronchus is narrowed or obstructed.
Multiple nodules, calcifications, and linear lesions are present in the upper lobes of both lungs, and scattered linear lesions are present in both lungs.
FDG uptake is normal.
A soft tissue nodule in the right pleura, approximately 1.3 cm in diameter, has increased FDG uptake, SUVmax=9.2.
Multiple soft tissue nodules and masses were observed in the right axilla, right supraclavicular fossa, right hilum, and mediastinum.
The largest, approximately 5.1*3.6cm, was located in the right axilla.
FDG uptake was increased, with an SUVmax of 16.3.
The cardiac silhouette appeared normal, with cardiac chamber density lower than myocardial density.
Calcification was observed in some arterial walls (including the coronary arteries).
No abnormal density shadows were observed in either breast, and FDG metabolism was normal.
No esophageal dilation, significant wall thickening, or masses were observed, and FDG uptake was normal.
The liver showed no significant abnormalities in shape or size, with smooth liver margins and no widening of the hepatic fissure.
Multiple dense nodules were observed within the liver, and FDG uptake was normal.
No significant widening of the main portal vein was observed, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder appears normal in shape and size, but the gallbladder wall is thickened, with patchy areas of increased density within the gallbladder.
Local FDG uptake is normal.
The pancreas appears normal in shape, with no obvious abnormal density in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is normal.
The spleen appears normal in shape, size, density, and FDG uptake.
A soft tissue density nodule adjacent to the spleen, approximately 1.4 cm in diameter, shows no abnormal FDG uptake.
A few exudative shadows are present around both kidneys, with no obvious abnormal density in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is normal.
Irregular soft tissue masses are present in the bilateral adrenal regions, with uneven density.
The left mass is larger, measuring 7.9*5.7 cm and 3.6*2.3 cm respectively, with increased FDG uptake (SUVmax = 15.9 and 13.6).
Stomach distension is poor, with slight thickening of the walls of the cardia, part of the gastric body, and antrum.
FDG uptake is increased, SUVmax=4.5.
Intestinal distension is unsatisfactory, with increased FDG uptake in some parts of the intestine, SUVmax=4.8, most notably in the ascending colon.
Uterus is normal in shape and size, with no abnormal density shadows, and FDG uptake is normal.
A cystic lesion in the left adnexal region, approximately 6.2*6.0cm in size, shows absent FDG uptake.
Bladder distension is poor, with no obvious positive stones seen.
Multiple soft tissue nodules and masses are seen in the porta hepatis, abdominoperineal mesentery, bilateral iliac vessels, bilateral pelvic walls, left iliac vessels, and left groin.
The largest is located beside the left iliac vessel, approximately 5.9*5.7cm in size, with increased FDG uptake, SUVmax=17.0.
Decreased bone density throughout the body, normal spinal alignment, marginal osteophyte formation in some vertebral bodies, bilateral L4 spondylolysis with anterior displacement of the vertebral body, multiple intervertebral disc bulges, and flattening of multiple vertebral bodies in the thoracolumbar spine.
Patchy FDG uptake is observed around the right hip, SUVmax=3.5.
The abdominal wall around the umbilicus is thin, with subcutaneous herniation of abdominal contents.
A well-defined subcutaneous cystic lesion measuring approximately 7.2*3.8cm is present on the left anterior chest wall, with absent FDG uptake.
No abnormalities were observed in bone marrow FDG metabolism.

Impression

1. A mass near the hilum of the right lung with increased FDG metabolism; a soft tissue nodule in the right pleura with increased FDG metabolism; multiple soft tissue nodules and masses with increased FDG metabolism in the right axilla, right supraclavicular fossa, right hilum, mediastinum, hepatic hilum, mesentery in the abdominoperineal cavity, bilateral iliac vessels, bilateral pelvic walls, left iliac vessels, left groin, and bilateral adrenal regions. All of these are considered malignant tumors, possibly right lung cancer with multiple metastases. A biopsy is recommended to confirm the pathology and rule out other possibilities.

2. Old lesions in the upper lobes of both lungs. Scattered post-inflammatory lesions in both lungs. Anemia changes, partial calcification of arterial walls (including coronary arteries).

3. Calcified lesions in the liver. Concentrated bile or sludge-like stones in the gallbladder. Accessory spleen. Left ovarian cyst.

4. Chronic inflammatory changes or physiological uptake in parts of the stomach wall and intestines; please follow up with endoscopy.

5. Osteoporosis, degenerative changes in the spine, bilateral L4 spondylolysis with anterior vertebral slippage. Multiple intervertebral disc bulges, multiple vertebral wedging deformities in the thoracolumbar spine. Right hip periarthritis. Umbilical hernia. Benign subcutaneous lesion in the left anterior chest wall, suggestive of a cyst.

6. Low-density thyroid nodule, normal FDG metabolism, suggestive of nodular goiter; please combine with ultrasound examination.

7. Age-related brain, deep lacunar infarcts.

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.
