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: Normal brain morphology and structure; small patchy low-density shadows were seen in the left frontal, parietal, and temporal lobes, the largest measuring approximately 1.4*0.8cm, with no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical and showed no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
The nasal septum was deviated, and the left nasopharyngeal wall was slightly thickened with increased FDG uptake (SUVmax = 3.0).
The pharyngeal recess was shallowed, and the palatine tonsils were symmetrical, with physiological FDG uptake.
The laryngopharynx was normal in morphology and structure.
The parotid and submandibular glands were normal in morphology and density, with physiological FDG uptake.
The thyroid gland was normal in morphology and size, with uniform density, and no abnormalities in FDG uptake.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
An irregular soft tissue mass, approximately 4.1*3.2cm in size, was found in the posterior segment of the right upper lobe near the hilum.
The mass had lobulated, spiculated margins and increased FDG uptake (SUVmax = 14.5).
A bronchus in the posterior segment of the right upper lobe was truncated.
A soft tissue nodule, approximately 2.2*1.9cm in size, was found in the apical-posterior segment of the left upper lobe.
It also had lobulated margins and increased FDG uptake (SUVmax = 16.8).
Multiple small solid nodules were observed in both lungs, predominantly subpleural, with clear borders.
The largest nodule was approximately 0.5cm in diameter.
FDG uptake was slightly increased (SUVmax = 1.2).
Both lungs showed increased translucency, multiple air-filled cavities, and scattered linear lesions.
FDG uptake was normal in both lungs.
There was no pleural effusion or pneumothorax bilaterally.
Lymph nodes were visualized at the right hilum, pretracheal vena cava, and main pulmonary artery window.
The largest node had a short diameter of approximately 1.6 cm, with increased FDG uptake and an SUVmax of 14.5.
The cardiac silhouette was normal.
Some arteries showed slight sclerosis.
The esophagus was not dilated, and the wall showed no significant thickening or mass; FDG uptake was not increased.
The liver was normal in shape and size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was normal in shape and size, with 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, no widening of the main pancreatic duct, and no significant abnormal FDG uptake.
The spleen was normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is normal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is adequately filled, with slight thickening of the gastric wall in the cardia and antrum, and slightly increased FDG uptake (SUVmax = 2.6).
Intestinal filling is unsatisfactory; no local masses are seen, but some intestinal segments show increased FDG uptake (SUVmax = 6.6).
The prostate is full and homogeneous in density, with no abnormally increased FDG uptake.
Calcification of the tunica vaginalis is present on the right side.
The bladder is poorly filled, with no obvious positive stones.
Numerous small lymph nodes are visible in the retroperitoneum and mesentery, the largest with a short diameter of approximately 0.8 cm; FDG metabolism is normal.
No obvious fluid accumulation is seen in the abdomen or pelvis.
The spinal alignment is normal, with some vertebral marginal osteophytes, and L4/5 and L5/S1 intervertebral disc bulges.
A small cystic shadow was seen in the right femoral head, with no abnormal FDG uptake observed.
No abnormalities were found in the FDG uptake of the entire skeleton shown.

Impression

1. a. Space-occupying lesions near the hilum in the posterior segment of the right upper lobe and in the posterior segment of the left upper lobe, both with increased FDG metabolism, suggestive of central lung cancer; multiple lymph node metastases in the right hilum and mediastinum. b. Multiple small nodules in both lungs, some with slightly increased FDG metabolism, suggesting possible metastasis, while others are chronic inflammatory nodules. c. Small patchy low-density lesions in the left frontal, parietal, and temporal lobes, with normal FDG metabolism, metastasis to be ruled out; contrast-enhanced MRI is recommended for clarification.

2. Bilateral emphysema. Scattered post-inflammatory lesions in both lungs. Minor arteriosclerosis in some arteries.

3. Benign prostatic hyperplasia. Calcification of the tunica vaginalis in the right testis. Reactive hyperplasia of retroperitoneal and mesenteric lymph nodes.

4. Chronic inflammatory changes in the cardia, antrum of the stomach, and part of the intestines; please follow up with endoscopy.

5. Degenerative changes in the spine, L4/5 and L5/S1 intervertebral disc bulges. Right femoral head hernia.

6. Chronic inflammation of the left lateral wall of the nasopharynx.

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.
