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.

There was no midline shift.
The morphology and contour of both eyeballs were normal, the retrobulbar structures were clear, and FDG uptake was normal.
Slight thickening of the right maxillary sinus mucosa was observed, while no significant thickening was seen in the other paranasal sinuses, and the sinus walls were intact.
Soft tissue thickening was observed on the lateral and posterior walls of the nasopharynx, with increased FDG uptake (SUVmax = 5.7).
The base of the tongue and both palatine tonsils were full, with physiological FDG uptake.
Increased FDG uptake was observed in the left alveolar process (SUVmax = 4.8).
The morphology and structure of the laryngopharynx are normal, and the parapharyngeal space is clear.
The size, shape, and density of the bilateral parotid and submandibular glands are normal, and FDG uptake is physiological.
The thyroid gland is normal in shape and size, with no obvious abnormal density shadows, and FDG uptake is normal.
Multiple lymph nodes are visible in the bilateral deep cervical spaces, submandibular region, and submental region.
The largest is located in the left superior deep cervical space, measuring approximately 0.8 1.0 cm, with increased FDG uptake (SUVmax = 4.1).
An irregular soft tissue nodule is seen beside the horizontal fissure in the medial segment of the right middle lobe, with clear borders, measuring approximately 1.5 1.3 1.0 cm, with relatively homogeneous density, increased FDG uptake (SUVmax = 9.2), and spiculated margins that traction on the adjacent pleura.
A few irregular strip-like shadows and punctate calcifications are seen in the anterior segment of the right upper lobe, with clear borders, increased FDG uptake (SUVmax = 1.6).
A solid nodule with a long diameter of approximately 1.0 cm was seen in the horizontal fissure of the right lung.
A small solid nodule with a long diameter of approximately 0.5 cm was seen in the anteromedial basal segment of the left lower lobe.
FDG uptake was normal.
A few patchy, linear shadows and multiple punctate calcifications were seen in both lungs.
FDG uptake was normal.
Slight thickening of the pleura was observed bilaterally, with a small amount of pleural effusion on the right side.
Small lymph nodes were visible in the hilar and mediastinal regions bilaterally, showing increased FDG uptake (SUVmax = 3.1).
The heart size was normal.
Calcification of the aorta and its branches (including the coronary arteries) was observed.
No obvious abnormal density shadows were seen in the fibroadenomas of both breasts.
FDG uptake was normal.
The esophagus was not dilated, and the wall was not significantly thickened or lumped.
FDG uptake was normal.
Gastric distension was poor, with slight thickening of part of the gastric wall.
FDG uptake was increased (SUVmax = 4.3).
Intestinal distension was unsatisfactory; no local masses were observed; FDG uptake was increased in some intestinal segments (SUVmax = 6.4).
The liver showed no obvious abnormalities in shape or size; the liver margins were smooth; and the hepatic fissures were not widened.
No obvious abnormal density shadows were observed in the liver parenchyma; FDG uptake was normal.
No dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size; the gallbladder wall was not thickened; no positive stones or obvious masses were observed; FDG uptake in the gallbladder fossa was normal.
The peripancreatic spaces were clear; no obvious abnormal density shadows were observed in the parenchyma; the pancreatic duct was not widened; and FDG uptake was normal.
The spleen was basically normal in shape and size; density and FDG uptake were normal.
The bilateral adrenal glands showed no abnormalities in shape, size, or density; local FDG uptake was normal.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the renal parenchyma, and FDG uptake is normal.
No widening of the renal pelvis, calyces, or ureters is seen bilaterally, but punctate high-density lesions are seen within the renal calyces bilaterally.
The bladder is poorly filled, and no positive stones are seen within the cavity.
The uterus is normal in shape and size, containing a high-density mass with multiple internal calcifications and a length diameter of approximately 3.0 cm; FDG uptake is normal.
No abnormal density shadows or increased FDG uptake are seen in the bilateral adnexa.
No enlarged lymph nodes are seen in the retroperitoneal region, and FDG uptake is normal.
No obvious effusion is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with osteophyte formation at some vertebral body margins and facet joints, multiple thoracic and lumbar intervertebral disc effusions, and multiple lumbar intervertebral disc bulges; FDG uptake is normal.
Increased FDG uptake in the soft tissues surrounding the left hip joint and both ischial tuberosities, SUVmax=3.9.

Impression

1. a. Irregular soft tissue nodule near the horizontal fissure in the medial segment of the right middle lobe, with increased FDG metabolism, highly suggestive of lung cancer; please refer to pathology. b. Chronic inflammatory nodules in the right horizontal fissure and left lower lobe. Old lesion in the anterior segment of the right upper lobe, with a few chronic inflammations and remnants in both lungs. c. Small amount of pleural effusion on the right side. Reactive hyperplasia of hilar and mediastinal lymph nodes in both lungs.

2. Low-density lesion in the right frontal lobe, possibly ischemic, space-occupying lesion to be ruled out; enhanced MRI is recommended for further examination.

3. Chronic inflammatory changes in the nasopharynx, possibly left-sided periodontitis; please refer to specialist examination. A few chronic inflammations in the right maxillary sinus. Reactive hyperplasia of bilateral cervical lymph nodes.

4. Manifestations of chronic gastritis; please refer to endoscopic follow-up. Physiological uptake of some intestinal segments is highly likely.

5. Small kidney stones in both kidneys. Uterine fibroids with calcification.

6. Degenerative changes in the spine, multiple thoracic and lumbar intervertebral disc effusions, multiple lumbar intervertebral disc bulges. Peritoneitis of the left hip joint and both ischial tuberosities.

7. Partial arteriosclerosis (including coronary arteries).

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.
