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; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities in FDG uptake were observed.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no significant abnormalities.
Slight thickening of the mucosa of the bilateral ethmoid and maxillary sinuses was observed, but the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; no abnormalities in FDG uptake were observed; the bilateral pharyngeal recesses were symmetrical; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear, and no abnormalities in FDG uptake were observed.
The bilateral palatine tonsils showed physiological uptake.
The morphology and structure of the laryngopharynx were normal.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with uniform density; no abnormalities in FDG uptake were observed.
Increased FDG uptake was observed in the left maxillary alveolar region, with SUVmax = 3.7.
A patchy soft tissue shadow was seen in the posterior segment of the right upper lobe, with a possible bronchial truncation.
The bronchus was poorly adhered to the pleura (including the interlobar fissure pleura).
FDG metabolism was elevated, with an SUVmax of 6.6.
Multiple punctate lesions were observed around the lesion.
Multiple focal low-density areas without pulmonary markings were seen in both upper lobes.
Several ground-glass nodules were seen in the left upper lobe, with relatively clear borders; the largest was approximately 0.4 cm in length.
Multiple small solid nodules were also seen in the remaining lobes of both lungs, the largest being approximately 0.5 cm in length.
FDG uptake was normal.
A small amount of arc-shaped fluid-density shadow was seen in both pleural cavities.
A small amount of pericardial effusion was observed.
The esophagus was not dilated, and the esophageal wall showed no significant thickening or mass; FDG uptake was not elevated.
Multiple enlarged lymph nodes were observed in the right hilum and mediastinum, locally fused into a mass, the largest measuring approximately 8.2 5.5 cm, with homogeneous internal density.
Lymph node shadows were also seen in the bilateral supraclavicular fossa, the largest with a short diameter of approximately 1.2 cm, showing increased FDG metabolism (SUVmax = 8.4).
The liver showed no obvious abnormalities in shape or size, with smooth borders and no widening of the hepatic fissures.
Plain CT scan showed no obvious abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no obvious widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Multiple cystic lesions were observed in both kidneys, the largest located on the right side, measuring approximately 2.1 2.5 cm, with no obvious abnormal FDG uptake.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Stomach distension was poor, with no significant thickening of the gastric wall, and FDG uptake was normal.
Intestinal distension was poor, with no significant thickening or mass in the intestinal wall, and FDG uptake was physiological.
The prostate was full in shape, with punctate high-density shadows inside, and FDG uptake was not abnormally increased.
The bladder was generally full, with no obvious positive stones.
A small lymph node was seen in the hepatogastric space, with a short diameter of approximately 0.6 cm, showing increased FDG metabolism (SUVmax = 2.7).
A small amount of fluid-density shadow was seen in the tunica vaginalis of both testes.
The spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies and L4/5 and L5/S1 intervertebral disc bulging, but FDG uptake was normal.
No abnormal FDG metabolism was observed in the entire skeleton. (Liver SUVmax = 2.7, mediastinal blood pool SUVmax = 1.8)

Impression

  1. a. A mass in the right upper lobe with increased FDG uptake; multiple enlarged lymph nodes in the right hilum, mediastinum, and bilateral supraclavicular fossa, some fused, with increased FDG metabolism, suggesting a high probability of right lung cancer with multiple lymph node metastases; tuberculosis to be ruled out; airway dissemination in the right upper lobe is also a possibility. b. Small lymph nodes in the hepatogastric interspace with increased FDG metabolism, suggesting reactive hyperplasia. Small amount of pleural effusion and pericardial effusion bilaterally.

  2. a. Ground-glass nodule in the left upper lobe, with normal FDG metabolism, suggesting atypical adenomatous hyperplasia or inflammatory nodule; annual HRCT follow-up is recommended. b. Multiple small chronic inflammatory nodules (solid) in the remaining lungs. Paraseptal emphysema in both upper lobes.

  3. Minor inflammation in the bilateral ethmoid and maxillary sinuses. Increased FDG uptake in the left maxillary alveolar region, suggesting inflammation. No obvious abnormalities were seen on cranial imaging.

  4. Multiple cysts in both kidneys. Benign prostatic hyperplasia with calcifications.

  5. Bilateral testicular hydrocele with small amount of fluid in the tunica vaginalis.

  6. Spinal osteophyte formation, L4/5 and L5/S1 intervertebral disc bulge.

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.
