Fig. 1A.74-year-old man with symptomatic adrenal metastasis from
small cell lung cancer. Transverse T2-weighted fast spin-echo MR image (TR/TE,
5447/134) for biopsy planning shows acute hemorrhage (arrow).
Fig. 1B.74-year-old man with symptomatic adrenal metastasis from
small cell lung cancer. Sagittal fluoroscopic fast imaging with steady-state
free precession image shows needle guidance towards lesion
(arrow).
Fig. 1C.74-year-old man with symptomatic adrenal metastasis from
small cell lung cancer. Sagittal (C) and Paraaxial (D)
breath-hold T2-weighted fast spin-echo MR images (1856/105, 5 slices in 14
sec) before biopsy show sampling from nonhemorrhagic parts of lesion
(arrow, D).
Fig. 1D.74-year-old man with symptomatic adrenal metastasis from
small cell lung cancer. Sagittal (C) and Paraaxial (D)
breath-hold T2-weighted fast spin-echo MR images (1856/105, 5 slices in 14
sec) before biopsy show sampling from nonhemorrhagic parts of lesion
(arrow, D).
Fig. 2.53-year-old woman with pheochromocytoma with needle placement
before biopsy. Transverse unenhanced T1-weighted three-section breath-hold
fast low-angle shot MR image (TR/TE, 54/7.4; flip angle, 70°; scanning
time, 7 sec) shows stylet partially withdrawn in 16-gauge cannula for detailed
depiction of its tip.
Fig. 3A.47-year-old man with large adrenal metastasis from
adenocarcinoma of lung. Sagittal MR fluoroscopic fast imaging with
steady-state free precession image (TR/TE, 17.8/8.1; flip angle, 90°)
shows angulated approach with 13-gauge cannula.
Fig. 3B.47-year-old man with large adrenal metastasis from
adenocarcinoma of lung. MR fluoroscopic image shows needle tip
(arrow) close to upper pole of kidney during expiration.
Fig. 3C.47-year-old man with large adrenal metastasis from
adenocarcinoma of lung. Continued MR fluoroscopic image shows target lowering
with inspiration.
Fig. 3D.47-year-old man with large adrenal metastasis from
adenocarcinoma of lung. MR fluoroscopic image shows needle advancement into
lesion with easy avoidance of pleura and kidney (asterisk). Only two
fluoroscopic series (each with 23-sec scanning time for 20 images) were
needed. Note that needle conspicuity and anatomic survey were not compromised
by low spatial resolution (48 x 128 pixels) of MR fluoroscopic
sequence.
