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: Normal brain morphology and structure, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
Widening of the ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal; midline shift was not observed.
Bilateral eyeballs were symmetrical with no obvious abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
Nasal septum deviation was observed, but no thickening of the nasopharyngeal wall was observed; both palatine tonsils were symmetrical, and FDG uptake was physiological.
Laryngopharynx morphology and structure were normal.
Bilateral parotid and submandibular glands showed normal morphology and density, with physiological FDG uptake.
Thyroid glands were normal in morphology and size, with uniform density; FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
Postoperatively, the patient presented with right lower lobe lung cancer.
Partial absence of the right 10th and 11th ribs and irregular cortical margins of the right 5th and 6th ribs were observed.
The right lower lobe was absent, and linear high-density shadows were seen at the bronchial stump.
FDG metabolism was normal.
The right upper lobe bronchus remained patent, with no definite space-occupying lesions.
FDG metabolism was normal.
Multiple hazy patchy and nodular shadows were observed in the right upper lobe, with the most prominent areas located in the apical-posterior segment of the right upper lobe.
FDG uptake was increased, with SUVmax = 5.6.
Scattered linear lesions were observed in the remaining two lungs, with no abnormal FDG uptake.
Right pleural thickening was accompanied by increased FDG uptake (SUVmax = 4.5), and right-sided loculated pneumothorax and effusion were present.
Right mediastinal deviation was observed.
Lymph nodes were visible in the right hilum, pretracheal vena cava, and aortic window, the largest with a short diameter of approximately 1.0 cm, showing increased FDG uptake (SUVmax = 3.6).
The cardiac silhouette was slightly enlarged.
Partial arteriosclerosis was observed, with linear high-density shadows seen in the coronary artery area.
The esophagus showed no dilation, thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver was normal in shape and size, with smooth borders, no widening of the hepatic fissure, and no abnormal density shadows in the liver parenchyma on plain CT scan; 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 obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
The spleen was normal in shape, size, density, and FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma; no widening of the renal pelvis, calyces, or ureters was observed, and FDG uptake was normal.
Bilateral adrenal glands showed no obvious abnormalities on contrast.
The stomach was adequately filled, with slight thickening of the gastric cardia and antrum walls, and a slightly increased FDG uptake (SUVmax = 2.5).
Intestinal distension was unsatisfactory, with no local masses observed.
FDG uptake was increased in some intestinal segments (SUVmax = 2.9).
Anal canal FDG uptake was also increased (SUVmax = 5.6).
The prostate was of normal size and uniform density, with no abnormally increased FDG uptake.
The left testis was not visualized.
The right inguinal canal was widened.
Bladder distension was poor, with no obvious positive stones observed.
No enlarged lymph nodes were seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes and slight bulging of the L4/5 and L5/S1 intervertebral discs.

Impression

1. a. Postoperative right lower lobe lung cancer, postoperative changes in the right chest wall, no signs of tumor recurrence in the surgical area. b. Right upper lobe bronchus is patent, no obvious space-occupying lesion, FDG metabolism is normal. c. Right upper lobe infection, anti-inflammatory treatment and follow-up examination are recommended to rule out other causes. Scattered post-inflammatory lesions in both lungs. d. Right pleural effusion and pneumothorax; right pleural thickening with possible inflammatory uptake, pleural metastasis to be ruled out, close observation is recommended. e. Chronic inflammatory lymph nodes in the right hilum and mediastinum. Slightly enlarged cardiac silhouette. Partial arteriosclerosis, linear high-density shadows seen in the coronary artery course.

2. Chronic inflammatory changes in the cardia, antrum of the stomach and part of the intestine, hemorrhoids are possible, please follow up with endoscopy. Right inguinal hernia is possible. Left testis not visualized.

3. Degenerative changes in the spine, L4/5 and L5/S1 intervertebral disc bulge.

4. In elderly patients with lacunar infarcts deep within the brain, please combine with MRI examination.

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.
